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
`((- 5 - 7))/((6 - 0))`) =
`(- 12)/(6)` = - 2

m =
