What is the equation for a vertical line passing through (7, -10)?

The equation is " x = 7 ".  The vertical axis letter "y" does not
figure into this, because ANY point with x = 7 is on that vertical
line, including the point (x,y) = (7,-10) .

By the way " y = -10 " is the equation for the horizontal line that
that passes through 7, -10 .

I hope this helps.  Write back if you have more questions.
