Answer:
- y = -3/5 × -5 - 2
- y = 2 × -1 + 2
Step-by-step explanation:
#1
- y = mx + b
- m = -3/5, x = -5, b = -2, y = y
- put in correct order
#2
- (2, -1) - (5,5) = 6/3 = 2/1 = 2 (remember, y is over x. The formula is y2 - y1 / x2 - x1)
- Pick either point given (2, -1) or (5, 5)
- Plug the point in
- y = y, m = 2, x = 2, b = -1
- Put in order

Answer:
x=8, y=10. (8, 10).
Step-by-step explanation:
-8x+7y=6
3x-2y=4
--------------
2(-8x+7y)=2(6)
7(3x-2y)=7(4)
-----------------------
-16x+14y=12
21x-14y=28
-------------------
5x=40
x=40/5
x=8
3(8)-2y=4
24-2y=4
2y=24-4
2y=20
y=20/2
y=10
