Answer: y =
(3)/(2)x - 8

Explanation:

1) Set the line given to you in y = mx + b form:

2y = 3x + 10


(2y)/(2) = (3x)/(2) + (10)/(2) (divide everything by 2)

y =
(3)/(2)x + 5

2) Since the lines are parallel, the slopes must be the same. Now that we know the slope of the line, use point slope form [
y - y_(1) = m(x - x_(1)) ] to find the equation of the line using the points given:

y - (-5) =
(3)/(2)( x - (2)) - insert the values into the equation

y + 5 =
(3)/(2)x - 3 - distribute 3/2

y =
(3)/(2)x - 8 - subtract 5 from both sides
