Alright.
For 7, you'll want to put congruent sides equal to each other, assuming they are parallelograms. So, you'll get the two equations:
3x+2=23
2y-7=9
Solve using GEMDAS/PEMDAS, and you'll get these answers.
3x+2=23
3x=21
x=7
2y-7=9
2y=2
y=1
For 8, you'll want to do the exact same thing, formatting the numbers to equal each other. You'll get these two equations:
3y+5=14
2x-5=17
Solving them would make:
3y+5=14
3y=9
y=3
2x-5=17
2x=22
x=11
For 9, you have to remember that the angle opposite of one angle in a defined parallelogram are congruent. Thus:
130=2h
5k=50
solve them and you get
h=65
k=10

Answer: y + 3 = 4 (x +1 )
Step-by-step explanation:
The eqution of a line in point- slope form is given as :
= m(
)
Where m is the slope and (
, 
) is the given point
substituting the values into the formula , we have:
y - (-3) = 4 ( x - {-1) )
y + 3 = 4 ( x + 1)
This is the equation of the line in point-slope form.
