Answer:
point form (-8,-3) equation form x=-8, y=-3
Step-by-step explanation:
Answer:
x = -8, y = -3
Step-by-step explanation:
x - y = -5
x - 8y = 16
Let’s start by the second equation!
x - 8y = 16
Solve for y
-8y = 16 - x
y = -2 + x/8
Now substitute that into the first equation
x - y = -5
x - (-2 + x/8) = -5
x + -1(-2 + x/8) = -5
x + (-1)(-2) + -1(x/8) = -5
x + 2 + -1/8x = -5
(x + -1/8 x) + (2) = -5
7/8x + 2 = -5
7/8x = -7
x = 8/7 • -7
x = -8
Then go back to the second equation…
x - 8y = 16
-8 - 8y = 16
-8y = 24
y = 24/-8
y = -3
x = -8, y = -3
Step-by-step explanation:
x - y = -5

x = 8/7 • -7
x = -8

-8 - 8y = 16
-8y = 24
y = 24/-8
y = -3
