Y=9(x^2+3x-x-3)
y=9(x^2+2x-3)
y=9x^2+18x-27
The answer is: [C]: " y = 3x + 1 " .

Note: By looking at the graph, we see that it passed through the point, " (0, 1) " (at the y-intercept).
_____________________________________________________
Consider choice: [A]: "y = 3x" ; When "x = 0" ; what does "y" equal ?
→ y = 3x = 3(0) = 0 ; → "(0, 0)" is a solution; NOT "(0, 1)" ; so rule out "[A]" .
________________________________________________________
Consider choice: [B]: "y = 3x − 1" ; When "x = 0" ; what does "y" equal ?
→ y = 3(0)−1 =0−1 = -1; → "(0, -1)" is a solution; NOT "(0, 1)" ; so rule out "[B]" .
________________________________________________________
Consider choice: [C]: "y = 3x + 1" ; When "x = 0" ; what does "y" equal ?
→ y = 3(0)+1 = 0+1 = 1; → "(0, -1)" is a solution; so "choice [C]" is possible.
________________________________________________________
Consider choice: [D]: "y = 3x² + 1"; When "x = 0" ; what does "y" equal ?
→ y = 3(0²)+1 = 0+1 = 1; → "(0, 1)" is a solution; so "choice [D]" is possible.
________________________________________________________
However; choice: [D]: is a parabola, not a line; so we determine that the correct answer is: Choice [C]: "y = 3x + 1" .

Answer:
got it
Step-by-step explanation:
Answer:
y = -
x + 1
Step-by-step explanation:
The equation of a line is: y = mx + c where m is the slope of the line and c is the y-intercept. I will be calculating the slope using the points (3, 0) and (0, 1).
Slope = 
= 
Thus, the slope of the line is -.
Based on the graph, the y-intercept is 1.
Thus, the equation of the line is: y = -x + 1.
2x - 7 = 2x - 14
2x = 2x - 7.
Matt is incorrect, there are actually 0 correct answers to this equation.
