Write the equation of a line that is parallel to x = 8 and that passes through the point (- 3, - 2) .

Question

I really don’t understand

Answer 1

With x=8, it means the line is vertical (up and down), it also means it is undefined.

In order to find the parallel line, it has to have the same slope. Different b value (mx+b, but the m has to be the same).

Since the question is asking for a parallel line, you know that it also has to be vertical, to keep it consistent.

Since it is asking for the line that passes through (-3, -2), you are looking at the x value which is -3, therefore x=-3

Answer 2

x = 8 is the equation of a vertical line parallel to the y-axis and passing through (8, 0).

A parallel line must be in the same form. In this case x = -3.
