c\) is the number where the line crosses the \(y\)-axis. This is the \(y\)-intercept. To draw a graph of \(y = mx + c\) for given values of \(x\): Use the pairs of values in the table to list the ...

use the scales of the axes and find how many units you go up or down for each unit you move right. To work out the equation of a line from a graph, find the gradient and the \(y\)-intercept.
