Find the gradient of the line passing through the points (-2, 0) and (0, 4)
A
2
B
-4
C
-2
D
4
correct option: c
Given (-2, 0) and (0, -4),
The gradient is of a line is the difference in height (y co-ordinates) ÷ The difference in width (x co-ordinates):
= \(\frac{-4 - 0}{0 - (-2)}\)
= \(\frac{-4}{2}\)
= -2
