Answer:
Ok
Step-by-step explanation:
Manipulate the first equation to
y = 22-7z
Then substitute in the second to find z
8(22-7z) + 7z = 127
176-56z+7z = 127
-49z = -49
z = 1
So y = 22-7(1) = 22-7 = 15
y = 15; z = 1
i’m not sure sorry about that

Answer:
Step-by-step explanation:
You are given the point (x1, y1) = (-2, 7) and slope m = 5, and asked to fill in the blanks in the point-slope form ...
y -y1 = m(x -x1)
Put the numbers in there and you get ...
y -7 = 5(x -(-2))
Simplifying the right side gives you ...
y - 7 = 5(x + 2)
Then the blanks are filled with {-, 7, 5, +, 2}.
