Question

Find the slope of the line
a) 4
b) 1
c) -1
d) -4

Answer 1

D

Explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 1, 3) and (x₂, y₂ ) = (0, - 1) ← 2 points on the line

m =
`(-1-3)/(0+1)` = - 4 → D

Answer 2

d) - 4

Explanation:

(-1,3) (0,-1)

slope = y₂ - y₁/x₂x- x₁

= -1 - 3 / 0 - [-1]

= -1-3 / 0+ 1

= -4/1

= - 4
