Step-by-step explanation:
do 4.50 divided by 5 to get .9
First Equation:

Second Equation can be written as:

Slope of first equation is -3/4 and slope of second equation is 3/4.
Slope of parallel lines must be equal, and slope of perpendicular lines are the negative reciprocal of each other. None of these conditions can be seen for given two equations.
So, the two lines are neither parallel nor perpendicular.
So correct option is C
#21 is 95 degrees
#22 is B
