Answer:
4. c
5. y=7/8x+1
6. y=-10x
7. y=2.5-7
8. y=1.2x
9. y=-5x-8
Explanation:
4. because the graph is in a negative direction and the point is higher than 0
5. non-proportional means it doesn't pass through (0,0)
6. the y-intercept would be 0 so there is no b
7. the slope would be positive because it says it goes from left to right
8. same explanation as 6
9. only one with both a negative slope and y-intercept
