Answer:
ok sorry i could not put this into a formula im have to go but i will show you a really easy way.
Step-by-step explanation:
for number 1 i got (7,-1)
This is because there is a slope of 1/1 between these two points. so i plotted the two points on the graph. The distance between the two points is 4. so i followed the slope 4 times and thats what i got.
The correct way for doing number 1 is using the distance formula i believe but im running out of time
for the second one i got (3, -1/2)
we do this by using the midpoint formula.
The first picture is for number one and the second for number 2

Answer:
a. x = 14
b. Perimeter = 77
Step-by-step explanation:
a. Based on the Triangle Proportionality Theorem:
Cross multiply
Add 2 to both sides
Divide both sides by 2
x = 14
b. Perimeter of ∆QRS = RQ + QS + RS = (2x - 2) + 13 + 17 + (21 - 7) + 7
Plug in the value of x
= (2(14) - 2) + 13 + 17 + 14 + 7
= 26 + 13 + 17 + 14 + 7
= 77
