Question

The equation of a line is y = -3x – 2. What are the slope and the y-intercept of the line?

A.
slope = -3 and y-intercept = 2
B.
slope = 3 and y-intercept = -2
C.
slope = 3 and y-intercept = 2
D.
slope = -3 and y-intercept = -2

Answer 1

D. slope = -3 and y-intercept = -2

Explanation:

Slope Intercept Form:

• y - y₁ = m(x - x₁) (original version)
• y = mx + b (simplified version)

The variables:

• m ⇒ represents slope
• b ⇒ represents the y-intercept

y = -3x -2

• m = -3
• b = -2

Answer 2

D

Explanation:

The slope if before the x so in this case it's -3.

The y-intercept is at the end so it's -2.
