Question

What is the slope of the line that cuts through the points (1, -5) and (3, 5)? a. 5 c. One-fifth b. -5 d. Negative one-fifth

Answer 1

(a)

Explanation:

calculate the slope m using the slope formula

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

with (x₁, y₁ ) = (1, - 5 ) and (x₂, y₂ ) = (3, 5 )

substitute these values into the formula for m

m =
`(5-(-5))/(3-1)` =
`(5+5)/(2)` =
`(10)/(2)` = 5
