None of them are correct.
4x+5y=7
y=3x+9
1) 4x+5(3x+9)=7 2) y=3(-2)+9
y= -6 +9
4x+15x+45=7 y=3
19x+45=7
19x= -38
x= -2
x is -2 and y is 3
Answer: y - 1 =
(x - 6)
<u>Step-by-step explanation:</u>
Point-Slope form: y - y₁ = m(x - x₁) <em>where m is slope and (x₁, y₁) is the point</em>
m =
(x₁, y₁) = (6, 1)
y - 1 =
(x - 6)
