Question

Find the slope of the line containing the points (4,9) and (6,-5).A: -5/11B: -7C: -11/5D: -1/7

Answer 1

x₁ = 4

y₁ = 9

x₂ = 6

y₂=-5

We will use the slope formula below;

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

substitute the values into the formula

`\text{slope =}(-5-9)/(6-4)`

`=(-14)/(2)`

`=-7`
