The y-intercept is a key element in the world of mathematics, particularly when dealing with linear equations and coordinate geometry. It represents the point where the graph of a linear equation ...

Graphing an equation is an essential skill in mathematics, as it helps us visualize the relationships between variables. There are several techniques that can be employed to make graphing easier and ...

The slope intercept form of a linear equation has the following form where the equation is solved for y in terms of x: ...

There must be a better way. If you’ve ever taught prealgebra or algebra 1, you know what I know: There is nothing about teaching the slope-intercept form of a line that is as easy as it should be. I ...

Any straight line graph has a constant gradient, which is calculated by the change in 𝑦 divided by the change in 𝑥, along any section of the graph. The gradient is measuring the steepness of the ...

To help draw a straight line graph from its equation, fill in a table of 𝑥 and 𝑦 values. Plot the pairs of values as coordinates and join to make a line. Make sure you are confident with ...
