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 ...

In this case both the slope and the y intercept are known and the equation can be written directly. For example if the slope is -2 and the y intercept is (0,6), then the equation is In this case the ...

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 straight line through two points will have an equation in the form \(y = mx + c\). We can find the value of \(m\), the gradient of the line, by forming a right-angled triangle using the ...

The straight line through two points will have an equation in the form \(y = mx + c\). Then, we can find the value of \(c\), the \(y\)-intercept, by substituting the coordinates of one point into the ...
