Answer:

C is the correct answer

Step-by-step explanation:

The pink one has a slope of 2 so 2x and a y-intercept at -3 : y=2x-3

The green one has a slope of negative 2 so -2x and a y-intercept at 1 : y=-2x+1

The solution to a system of equation are the true values of the equations.

The system that shows the solution on the graph is: [tex]\mathbf{y = 2x -3}[/tex] and [tex]\mathbf{y = -2x + 1}[/tex]

The pink line

The points on this line are (4,5) and (3,3)

Start by calculating the slope (m)

[tex]\mathbf{m = \frac{y_2 - y_1}{x_2 - x_1}}[/tex]

[tex]\mathbf{m = \frac{3-5}{3-4}}[/tex]

[tex]\mathbf{m = \frac{-2}{-1}}[/tex]

[tex]\mathbf{m =2}[/tex]

The equation is then calculates as:

[tex]\mathbf{y = m(x - x_1) + y_1}[/tex]

So, we have:

[tex]\mathbf{y = 2(x - 3) + 3}[/tex]

[tex]\mathbf{y = 2x -6 + 3}[/tex]

[tex]\mathbf{y = 2x -3}[/tex]

Hence, the system that shows the solution on the graph is:

[tex]\mathbf{y = 2x -3}[/tex] and [tex]\mathbf{y = -2x + 1}[/tex]
