Question

What is the gradient?

Answer 1

The gradient (slope) is -4.

Explanation:

Note that two points on the graph through which the blue line passes exactly are (-2, 5) and (0, -3). As we move from the first point to the second, x increases by 2 (the 'run') and y (the 'rise') decreases by 8. Thus, the gradient, or slope, of this line is m = rise/run = -8/2, or m = -4.

Answer 2

`{ \tt{gradient = ( - 3 - 1)/(0 - ( - 1)) }} \\ = ( - 4)/(1) \\ = - 4`
