Answer:^^

Step-by-step explanation:

So, for perpendicular equations, the slope is flipped and "negated." (depends) here's an example "y=mx+b" if the original is y=3x+b (b doesnt matter rn) and it asks for the perpendicular of that equation, it would simply be y=-1/3x+b. Originally, our slope is positive 3 or 3/1. First we add the opposing side which in this case would be negative. Making -3 or -3/1. Now we must flip it to -1/3. Every whole number automatically has a "1" under it as a denominator.  For #19 we would make it y=-4/3x+5 as our perp equation. Then just plug in 3(x) and -3(y). (-3)= -4/3(3)+5.

Same for 22! hope this helps
