Complete the equation of the line through (-1,6) (7,-2) like y= ? ?

Find the slope first, use the formula (y₁-y₂)/(x₁-x₂)

[6-(-2)]/(-1-7) = 8/-8 -> -1              Therefore your slope (mx) is -x.

To find the y-intercept, you use one of the points and substitute it in the slope intercept formula: y=mx+b, using the slope you just found.

-2=-1(7)+b

-2=-7+b -> -2+7=b

b=5

In conclusion, your equation will be y=-x+5. I hope this helped ;)

the 4th choice is the correct one

step-by-step explanation:

x> 6

step-by-step explanation:

8x+8> 7x+14

8x-7x> 14-8

x> 6
