Question

The diagram shows the straight line L, points A(-9,-1), M(-3,2) and C are points on L

Answer 1

The gradient of the line
`L_1\\` , based on points A(-9, -1) and M(-3, 2), is 0.5 or
`(1)/(2)`.

How do we calculate the gradient of the line?

The gradient (or slope) of a straight line can be found using the coordinates of any two points on the line. The formula to calculate the gradient m between two points A(x₁,y₁) and M(x₂,y₂) is given by:

m = (y₂ - y₁)/(x₂ - x₁,)
m = 2−(−1)/−3−(−9)

m = 3/6

m = 1/2
