Question

What is the slope of the line? A. 2 B. -2 C. 1/2 D. -1/2

Answer 1

slope m = - 2 → B

calculate m using the ' gradient formula '

m = (y₂ - y₁)/(x₂ - x₁)

choosing 2 'clear ' coordinates from the graph of the line

(x₁, y₁) = (0, 7) and (x₂, y₂) = (7, - 5$\frac{(- 5 - 7)}{(6 - 0)}$) = $\frac{- 12}{6}$ = - 2

m =
