Answer:
7=-4x+7
Step-by-step explanation:
the formula of slope intercept form is y=Mx+b and M=slope and b=y value of x intercept
so y=-4x+7
Times 2nd equation by 2
add to first equation
3x+6y=6
<u>4x-6y=8 +</u>
7x+0y=14
7x=14
divide both sides by 7
x=2
sub back
2x-3y=4
2(2)-3y=4
4-3y=4
minus 4 both sideds
-3y=0
y=0
(x,y)
(2,0)
Answer: c
Step-by-step explanation:
