straight-line distance of 8 kilometers from Frank's house to Michelle's house. How far is Jen's
house from Frank's house? If necessary, round to the nearest tenth.

19. y=5x+-1

20. y=-2.5x+4

Step-by-step explanation:

19: 9-4=5

-1+5=4 so m=5

b=-1

so y=5x+-1

20: -1-1.5=-2.5

4+-2.5=1.5

so m=-2.5

b=4

so y= -2.5x+4
