Best ResponseYou've already chosen the best response.1\[y=mx+c\]They want you to find the yintercept, c. So you need to calculate the gradient, m.\[m={\Delta y \over \Delta x}={{y_1  y} \over {x_1  x}}\]You have two points, plug them in and find the gradient. Then substitute the gradient and one of the points into the line equation, and solve for c.
