Answer:
y=-1/4x+1/4
Step-by-step explanation:
You first will need to find the slope using these points, you will take -1 minus 2 over 5 minus -7. simplify that to get the slope.
After that you need to sub in points to find the y intercept. I chose (-7,2)
so it would be 2=-1/4(-7) + b
that would make 2=7/4 + b
simplify again to get 1/4 = b
then make the equation
