$x + 3y = 7 \\ 2x + 4y = 8 \\ x = 7 - 3y \\ 2(7 - 3y) + 4y = 8 \\ 14 - 6y + 4y = 8 \\ 14 - 2y = 8 \\ - 2y = - 6 \\ y = 3 \\ x = 7 - 3(3) \\ x = 7 - 9 \\ x = - 2$

Determine the equation of the line shown in the graph: y = −1 y = 0 x = −1 x = 0

BaLLatris [955]

Answer:

Option C.

Step-by-step explanation:

If a vertical line intersects the x-axis at point (c,0), then the equation of line is x=c.

From the given figure it is clear that it is a vertical line and it intersects the x-axis at (-1,0). There are infinite values of y at x=-1.

So, the equation of given line is

$x=-1$

Therefore, the correct option is C.
