Answer: -5,-1
Step-by-step explanation:
The fastest way to find the missing endpoint is to determine from the known endpoint to the midpoint and then performing the same transformation on the midpoint.
I'm going to try to let you answer this yourself so you can learn for yourself ok. :3
It must have the same slope as the given line, so
m = -A/B = -1/-2 = 1/2
So far, we have
y = mx + b = x/2 + b
Use the given point to find b.
4 = -2/2 + b = -1 + b
b = 5
y = x/2 + 5
Multiply through by 2.
2y = x + 10
Standard form:
x - 2y = -10
X=36 this is because you first have to multiply both sides by nine to get rid of the fraction, then you divide both sides by eight to get the x alone
Whole numbers include counting numbers and 0
