Answer:
use photomath and if that dont work use m a t h w a y
Step-by-step explanation:
Combine like terms
Y=-9x+8
And your slope would be -9
Answer: y= -6x -7
Step-by-step explanation:
Point slope formula : y-y1=m(x-x1)
y- (-1)=-6(x- (-1))
y+1= -6(x+1)
y+1= -6x-6
y+1-1=-6x-6-1
y=-6x-7
Standard from 6x+y=7
