Question

If a line goes through points (-2, 9) and (0, 3), what is its slope?

Answer 1

Answer:

b. -3

Step-by-step explanation:

slope = y2 - y1 / x2 - x1

= 3 - 9 / 0 + 2

= -6 / 2

= -3

Answer 2

Answer:

b

Step-by-step explanation:

calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (- 2, 9 ) and (x₂, y₂ ) = (0, 3 )

m = $\frac{3-9}{0-(-2)}$ = $\frac{-6}{0+2}$ = $\frac{-6}{2}$ = - 3
