Question

1)Calculate the gradient between 1,4 and 4,19.

2)Calculate the gradient between 3,9
5,5
3)Calculate the gradient between -3,4 and -1, 18

Answer 1

1. the gradient between (1,4) and (4,19) is:

(19 - 4) / (4 - 1) = 15 / 3 = 5

2. The gradient between (3,9) and (5,5) is:

(5 - 9) / (5 - 3) = -4 / 2 = -2

3. The gradient between (-3,4) and (-1,18) is:

(18 - 4) / (-1 + 3) = 14 / 2 = 7
