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 ...

Plotted points ... line will be of the form \(x = …\). If the \(y\)-coordinates are the same, the equation of the line will be of the form \(y = …\). The equation of a straight line on a graph ...
