Help ill mark you brainlist write in y=mx+b form

In the form y=mx+c it is y=-10/7x-45/7

Step-by-step explanation:

We use the formula y-y1=m(x-x1) where m is the slope given by (y2-y1)/(x2-x1)

m=-5-5/-1-(-8)

m=-10/7(plug it into the formula and simplify)

y-5=-10/7(x-(-8)

y-5=-10/7(x+8){multiply through by 7}

7y-35=-10(x+8)

7y-35=-10x-80 (make y the subject)

7y=-10x-80+35

7y=-10x-45(divide through by 7)

y=-10/7x-45/7
