Answer:
Step-by-step explanation:
- - 9x - 5y = -18
- 4x + 5y = 33
<u>Add up the two equations:</u>
- -9x - 5y + 4x + 5y = -18 + 33
- -5x = 15
- x = -3
<u>Finding y:</u>
- -9*(-3) - 5y = -18
- 27 - 5y = -18
- 5y = 27+18
- 5y = 45
- y = 9
Answer is: (-3, 9)

Answer:
1. y=
5
/4
x −2
2.x=−4y+76
The slope is 2
y=2x + b
Plug in a point to solve for b
8 = 2(3) + b
8 = 6 + b
b = 2
The equation is y = 2x + 2
3+ x/4=8
