1/2x = -1/2x
- Subtract 4 from both sides
1/2x - 4 = -1/2x - 4
(x-8) / 2 = (-x-8) / 2
(x - 8) / 2 = (-x-8) / 2
2(x - 8) = 2(-x - 8)

Answer:
y = 2x - 3
Step-by-step explanation:
the formula for finding equation of a line is m = (y2 - y1 )/(x2 - x1). that is (7-3)/(5-3) which gives you 4/2 = 2.
you then chose one of the point and fill in the equation y - y1 = m (x -x1)
So let's chose (3,3) and fill in.
y - 3 = 2 (x - 3)
y - 3 = 2x - 6
y - 2x = -6 + 3
y - 2x = -3
Hence, the equation of the line is y = 2x - 3
