<u>Answer:</u>
(x, y) = (-2, 2)
<u>Step-by-step explanation:</u>
We are given the following two equations which we are to solve using the substitution method:
--- (1)
--- (2)
From equation (1):

Substituting this value of x in (2) to get:
[/tex]
y = 2
Substituting the value of y in (1) to get x:
x = -2
Therefore, (x, y) = (-2, 2).
Answer:
a) m = 3 b = 1/5
b) y = 1/2x - 3
Step-by-step explanation:
y=mx+b
Answer:
You have to know the basic properties of exponents.
Jill's answer is wrong because you add the powers when there are like bases. You don't multiply.

-3+6=3
The base stays the same.
