New ReviewIn this video we are going to focus on mistakes that students make when they need to solve a system of equation by graphing the system.

New ReviewLet's master how to solve quadratic equations in some easy to understand steps. In this video we will cover the square root method, factoring out the GCF, factoring trinomials and using the quadratic formula.

New ReviewWhile this may look like two linear equations we are actually working with a linear equation and a reciprocal equation.

New ReviewLet's tackle how to factor a quadratic like this one. When you have a fraction as the middle term there are some things you need to know.

New ReviewUsually I recommend that students solve simultaneous equations using substitution when an equation is not linear but in this example you can actually using substitution or elimination.

In this math video we will learn how to solve a nonlinear system of equations. We are given two equations - one is a quadratic equation and one is a linear equation - and four possible solutions. We are told that the system has one...

HS.A-REI.D.11 Explain why the x-coordinates of the points where the graphs of the equations y = f(x) and y =...

A video entitled "Linear Function Equations" which discusses slope-intercept form in a hiking example.

Pupil outcome: I can read and interpret points from a graph to solve problems. Key learning points: - If you have one value, you can use a linear graph to find its pair. - The pair of values will satisfy the linear equation. - If the x...

Pupil outcome: I can calculate the volume of a frustum of a cone. Key learning points: - The frustum of a cone can be thought of as a cone with the top missing. - The volume of a frustum of a cone can be thought of as the difference...

Pupil outcome: I can understand that an equation needs to be in a format to be ready to be solved, through collecting like terms on each side of the equation. Key learning points: - An equation with both a multiplicative and additive...

Pupil outcome: I can draw a linear graph efficiently and accurately. Key learning points: - By choosing pairs of values that satisfy the equation, you can draw it accurately. - For linear graphs, only two pairs of coordinates are...

Pupil outcome: I can recognise that there are many different types of equations of which linear is one type. Key learning points: - An equation is a statement that two expressions are equal, indicated by =. - Linear expressions can be...

Pupil outcome: I can recognise the determining features of the shape of the graph from its equation. Key learning points: - The gradient of the line is determined by m when the equation is in the form y = mx + c - The y-intercept is...

Pupil outcome: I can recognise that the point of intersection of two linear graphs satisfies both relationships and hence represents the solution to both those equations. Key learning points: - More than one linear graph can be drawn on...

Pupil outcome: I can evaluate different problems to ascertain when rearranging a formula is beneficial. Key learning points: - Formulae are used in a variety of places, such as the science lab but also in factories. - Rearranging the...

Pupil outcome: I can solve two linear simultaneous equations graphically (0 or 1 or infinitely many solutions). Key learning points: - You can use your knowledge of linear graphs to draw the graphs of both equations on the same axes. -...

Pupil outcome: I can draw a linear graph from its equation and relate the features of the graph to its equation. Key learning points: - It is possible to identify the gradient and y-intercept when the equation is written in the form y =...

Pupil outcome: I can explore how to solve linear equations graphically via dynamic software. Key learning points: - A linear expression expressed on a graph represents a straight line. - This line can be used to find one variable when...

Pupil outcome: I can appreciate that writing linear equations in the form ay + bx + c = 0 may be more appropriate. Key learning points: - Linear equations can be written in multiple forms. - One of these forms is ay + bx + c = 0. - This...

Pupil outcome: I can use my knowledge of perimeter, area and volume to solve problems. Key learning points: - The volume and surface area of shapes made from prisms and cylinders can be found. - The volume and surface area of shapes made...

Pupil outcome: I can calculate and use theoretical probabilities for combined events using Venn diagrams (2 events). Key learning points: - The probability of an outcome can be found by considering a Venn diagram showing all possible...

A literal equation is an equation with more than one variable. These problems will sometimes have you solve for a variable, so that your solution is in terms of other variables. This will happen very often in formulas for science.

How to solve word problems using point-slope form of a line. Typically, students are very comfortable using slope-intercept form of an equation, but we rarely see examples where using point-slope form is the most efficient. In this...
