The line with slope - 8 passing through (-11,7)

Y = mx + b

slope (m) = - 8

(-11,7) ... x = - 11 and y = 7

now we sub into the formula and find b, the y int

7 = - 8 (-11) + b

7 = 88 + b

7 - 88 = b

- 81 = b

so ur equation is : y = - 8x - 81 or 8x + y = - 81 depending on what form u need it in
