Select the correct answer.
The equation of a line is y=-3x - 2. What are the slope and the y-intercept of the line?
OA.
slope = -3 and y-intercept = 2
ОВ.
slope = 3 and y-intercept = -2
OC.
slope = 3 and y-intercept = 2
OD.
slope = -3 and y-intercept = -2
Please help

Answer 1

• y=-3x-2

Compare to slope intercept form of line y=mx+b

• Slope=m=-3
• y intercept=b=-2

Option D

Answer 2

• D. slope = -3 and y-intercept = -2

Explanation:

Slope- intercept form:

• y = mx + b, where m is the slope, b is the y-intercept

The equation of a line is y= -3x - 2:

• m = -3, b = -2

Correct choice is D
