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 shorts video we will determine which graph is a linear function. We will first determine which of the four graphs is linear by understanding linear means a straight line. We will then learn how to determine which graph is a...

In this Algebra 1 video, students quickly analyze a table of values and four possible functions to determine which function best represents the data. We begin by noticing the domain increases by 1 each time, but the range does not have a...

This video explains the difference between Git rebase vs Merge.

A video entitled "Determine Intersect by Points" that covers determining whether a pair of lines, given as pairs of points, are intersecting, parallel, or coincide.

A video entitled "Compare and Contrast Functions" that covers which features of linear functions can be compared to draw conclusions in real-world contexts.

A video entitled "Solve Real World Situations" that covers solving a system of equations modeled by a real-world situation and interpreting the solution.

A video entitled "Graph and Estimate Solution" that covers graphing linear equations using x- and y-intercepts to solve systems of linear equations.

A video entitled "Lines through the y-Axis" that covers writing equations of lines graphed on the coordinate plane.

A video entitled "Lines through the Origin" that covers the process of graphing linear equations of the form y equals mx.

A video entitled "ID Functions by Equation" that covers characteristics of equations that are functions and characteristics of equations that are not functions.

Pupil outcome: I can describe a landscape from a map. Key learning points: - Landscapes can be described through their relief and drainage. - Landscapes can be described through their vegetation cover and land use. - Landscapes can be...

Pupil outcome: I can use my knowledge of graphical representations to solve problems. Key learning points: - When presented with a real-life problem, it can help to sketch what is happening. - A sketch can provide a visual aid for...

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 relate the solutions (0, 1 or 2) of a linear and quadratic pair of simultaneous equations to the graphs of these equations. Key learning points: - You can use your knowledge of graphical representations to draw the...

Pupil outcome: I can identify how cams create movement. Key learning points: - Cams usually convert rotary motion into linear motion. - Rotary motion is movement that goes round. - Oscillating motion is moving to and fro around a pivot...

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: - You can use your knowledge of linear graphs...

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 use my knowledge of interpreting real-life graphs to solve problems. Key learning points: - Real life graphs present a visual model of a situation. - Linear graphs are not always the best representation. - The...

Pupil outcome: I can use my knowledge of non-linear graphs to solve problems. Key learning points: - The shape of the graph can be used to identify the form of its equation. - If the graph has a context, then the solutions should be...
