Write an equation of the line that passes through (1, -5) and is parallel to 4x - 2y = -5

Answer 1

The problem does not specify in what form to give the answer so we will stay with general form.

Ax + By = C

Parallel lines have identical slopes so we can say

4x - 2y = C or 2x - y = C

We will find C by plugging in the known point.

2(1) - (-5) = C

2 + 5 = C

C = 7

2x - y = 7
