Find the gradient of this line?

Gradient = -2/1 or -2
The gradient is negative when the line moves down from left to right

Find the gradient of this line?

Gradient = 10/5 or 2

The gradient is positive when the line moves up from left to right
Find the gradient of this line?

Gradient = -4/2 or -2
The gradient is negative when the line moves down from left to right
