You can put this solution on YOUR website!
a) y = -x + b
use (-1,1) to find b
1 = -1(-1) + b
b = -1
y = -x -1

Write an equation for each line described below.
a) passes through (-1,1) with slope -1
b) has slope -5/7 and y-intercept 6
PLEASE HELP ME

a) y = mx + b
1 = - 1(- 1) + b ------- Substituting - 1 for m, and (- 1, 1) for (x, y)
1 = 1 + b
1 - 1 = b_____0 = b
Equation needed:
b) y = mx + b
Equation needed: ------- Substituting for m, and 6 for b
