Question 1081157: Please help me solve this problem: Write an equation that passes through the point (4, 2) and is (A) parallel and (B) perpendicular to the line y=2x-3. I tried solving a few pairs of coordinates for y=2x-3 such as (0, -3), (1, -1), (2, 1), (3, 3), (4, 5), and (5, 7). Please help on this question. Thank you!

Line passing through (4,2) and parallel to y=2x-3
, substituting for the coordinates of the point
-
Line through (4,2) and perpendicular to y=2x-3
(Now the slope you want to use must be negative reciprocal of the slope of the given line; given line slope is 2, so slope for a line perpendicular will be .)
-----same formula for b as before, but now use slope ;
