Question

Which of the following lines is parallel to x = 7?

3y = 7
y = 7
x = y
x = 4

Answer 1

The lines parallel to x=7 are x = a, where "a" is a constant.

So the last answer is true: x=4

Answer 2

D) x = 4

Explanation:

The given line is x = 7.

This is a vertical line passes through the points (7, 0) (7, 1) (7, -1)......

Here the value of x coordinate do not change, it is a constant, the value of y-coordinate changes.

So, any equation x = a, (where "a" is the constant) represents the vertical line.

From the given choices.

x = 4 (4 is a constant)

Therefore, the x = 4 is parallel to the given equation x = 7.

Remember, in parallel equations, the slope will be the same.
