Question

What is the equation, in slope-intercept form, of the line that passes through (0, −2) and has a slope of −3? (5 points)

A)y = −3x − 2
B)y = −3x + 2
C)y = −2x + 3
D)y = −2x − 3

Answer 1

Slope m=-3

Point (0,-2)

Equation of line Y=mx+b

Find b?

Substitute

Y=mx+b; m=-3, y=-2,x=0

-2=-3(0)+b

-2=b

Equation is

Y= -3x-2
