Given the linear equation 5y = 3x + 19, find
(a) the slope of a line perpendicular to the given line.
(b) the slope of a line parallel to the given line.
A. (a) 5/3 (b) 3/5
B. (a) 3/5 (b) 5/3
C. (a) 5/3 (b)3/5
D. (a) 3/5 (b)5/3

Rewrite the equation as:
y=(3/5)x + 19/5
which makes the slope as (3/5)
Lines that are parallel have the same slope.
Two lines that are perpendicular to each other have the product of the slope equal to 1.
That should be enough for you to make the right choice.
