Question

2. Calculate the slope of a line passing through the points (-2,4),(-1,1), and (1, - 5).

Answer 1

To find the slope, we will use the formula;

`\text{slope}=(y_2-y_1)/(x_2-x_1)`

x₁ = -2 y₁= 4

x₂ = 1 y₂ =-5

substitute the values into the formula and then evaluate

`\text{slope =}(-5-4)/(1+2)`

`\text{slope}=(-9)/(3)`

slope = -3
