Gradient = slope = rate of change of function
The function increases by 8 as the independent variable goes up by 4, resulting in a rate of growth of 8 / 4, or simply 2 as a unitary rate.

gradient
= slope
= rise/run
= (change in the value of y) / (change in the value of x)
If the points have coordinates (x1,y1) and (x2,y2), then
slope = (y2 - y1)/(x2 - x1)
Since the line passes through (-3,1) and (1,9),
slope = (9 - 1)/[1 - (-3)]
slope = 8/4 = 2
Therefore the gradient of that line is 2.

(9 - 1) / (1 - (-3)) = 8 / 4 = 2
