D
y= 3x-2

Answer 1

C, y=-8

Explanation:

Which equation represents the line that is parallel to y= 3 and passes through (-2,-8)?

y=3 means the y value is always 3, so the line is horizontal and parallel to the y axis.

A, x= -2 this is a vertical line

B. x= 3 this is a vertical line

C, y=-8 this is a horizontal line, where y is always -8 so it is parallel and will pass through -2

D, y= 3x-2 this line will be at an angle

Answer 2

y = -8

Explanation:

y = 3

is a "flat" horizontal line, which means every point on that line has the same y value no matter what x value we would consider.

any line parallel to that is then also a horizontal line with a constant y value. which y value ? well, the y coordinate of the given point tells us : (-2, -8)

so, the line equation is

y = -8
