#1
the answer would be C.) y = -2x + 4
here is why:
start with y = mx +b
imput the slope and the coordinates:
-8 = -2 x (6) + b
then solve for b
-8 = -2 x (6) + b
-8 = -12 + b
b = 4
so then the equation would be
y = -2x + 4
#2
y - 3 = 2 ( x - 7)
y - 3 = 2x - 14
y = 2x - 11
because none of the answers are in standard y=mx+b form I would say that the answer would be none.
