Question

What is the slope of the line that passes through the points (-20, 18) and (30, 14)?

Answer 1

slope = -
`(2)/(25)`

Explanation:

Calculate the slope m using the slope formula

m =
`(y_(2)-y_(1) )/(x_(2)-x_(1) )`

with (x₁, y₁ ) = (- 20, 18) and (x₂, y₂ ) = (30, 14)

m =
`(14-18)/(30-(-20))` =
`(-4)/(30+20)` =
`(-4)/(50)` = -
`(2)/(25)`

Answer 2

-2/25

Explanation:

Use the slope formula: rise/run to find the slope
