Question

Which equation represents a line which is

parallel to y = 0?
Answer
○ y = x
O x=-1
○ y = x − 4
-
○ y = −7

Answer

Answer 1

y = -7

Explanation:

y = 0 means the x-axis because it has a y-value of 0. Now, we know that any line parallel to another has to have the same slope. Immediately, we know that the first three options do not work because they do not have a slope of 0.

The x-axis and y = -7 both have a slope of 0 so due to that, they are parallel.

Try to draw it out so it makes more sense.
