Question

What is the slope of the line graphed below?

(-1, 3)
〒2,17
O A. ‡
О B. -4
O c. -¼
O D. A

Answer 1

D

Explanation:

calculate the slope m using the slope formula

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

with (x₁, y₁ ) = (- 2, - 1) and (x₂, y₂ ) = (- 1, 3) ← 2 points on the line

m =
`(3-(-1))/(-1-(-2))` =
`(3+1)/(-1+2)` =
`(4)/(1)` = 4
