What system of equations is shown on the graph below?
erma4kov [3.2K]

Answer:

The equation of the line passing through the points (-2,0) and (0,-4)

\frac{y - y1}{x - x1}  =  \frac{y2 - y1}{x2 - x1}

\frac{y - 0}{x  - ( -  2)}  =  \frac{ - 4 - 0}{0 - ( - 2)}  =  \frac{ - 4}{2}  =  - 2

y =  - 2(x + 2) \\ y =  - 2x - 4

2x + y =  - 4

The equation of the line passing through the points (0,-2) and (4,0)

\frac{y - y1}{x - x1}  =  \frac{y2 - y1}{x2 - x1}  \:

\frac{y - ( - 2)}{x - 0}  =  \frac{0 - ( - 2)}{4 - 0}

\frac{y + 2}{x}  =  \frac{1}{2}

x - 2y = 4

Option B

x minus 2 y = 4 and 2 x + y = negative 4
