Answer:
y=-3x+10
Step-by-step explanation:
Use point-slope form first.
y-y1=m(x-x1)
Plug the numbers into that.
y+2=-3(x-4)
Distribute and simplify to convert it to y=mx+b
y+2=-3x+12
y=-3x+10
Distribute the two to each of the values in the parentheses.
-4 +6a-10= 1-1a
Then move like terms to the same side to simplify.
6a+1a=1+10+4
7a=15
a=15/7
The answer is c I hope that helps
