If you mean: y = 3x+5 and y = 2x-7 then x = -12 and y = -31
The slope of a line perpendicular to one with slope m is -1/m. So for a line with slope 1/7, any line perpendicular to it will have: slope = -1 / (1/7) = -7
-7
The line in a fraction means "divided by." 7/9 = 7 divided by 9.

Many Europeans write a 1 with a rather long "flag" at the top but no cross mark at the bottom, so that a 1 and a 7 can sometimes be mistaken for one another. The line through the 7 distinguishes it in the way that the line through a Z can distinguish it from a 2.
