Please help me answer these and tell me how you got it ​

Step-by-step explanation:

A line has the form y=mx+b where m is the slope and b is the y intercept.

m=(y2-y1)/(x2-x1) in this case

m=(8-7)/(5-10)=-1/5 so the line is

y=-x/5+b, using point (5,8) we can solve for b

8=-5/5+b

8=-1+b

b=9

y=-x/5+9 or more neatly

y=(-x+45)/5

i believe it is c.y = 9x
