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 equation of a straight line on a graph is made up of a \(y\) term ... so the line will cut the \({y}\) axis at \(-2\). All the points that lie on the green line have a \(y\)-coordinate ...
