The gradient tells you the steepness of the line, and which direction it
goes. If the gradient is a positive number, the line goes up from left to right-
if it's negative it goes down from left to right.
The gradient is the coefficient of x. In y=5x-2, the gradient is 5x. That mean
for every one across it goes UP 5 squares. So that's going to be a steep
upward line.
The y intercept is the other number, so that's -2. So the line will be steep,
diagonally up and will go through -2 on the y axis.
