Equal to.
The graph is the same equation as y=-2x+8
Answer:

Step-by-step explanation:
6x - y = 31 so y = 6x - 31
substitute y = 6x - 31 into 3x + 7y = 8
3x + 7y = 8
3x + 7(6x - 31) = 8
3x + 42x -217 = 8
45x = 225
x = 5
y = 6x - 31
y = 6(5) - 31
y = 30 - 31
y = -1
answer
x = 5 and y = -1
Answer:2
Step-by-step explanation:
You use the slope equation so -11 -(-1) would be -11+1 because the negatives cancel each other out and you get -10. Then 4-9 is -5 and then -10 divided by -5 is a positive 2.
