The graph below represents the linear equation y = one-half x minus 3. On a coordinate plane, a line goes through (0, negative 3
mamaluj [8]

Answer:

(C) (2, -2)

Step-by-step explanation:

Given the linear equation: y=\dfrac12x-3

A second linear equation is given by the table:

\left|\begin{array}{c|cccccc}x&-1&0&2&3\\y&1&0&-2&-3\end{array}\right|

Clearly, this is a graph of y=-x as each y-value is a negative of its x-value.

Therefore if:

y=\dfrac12x-3;$and $\\y=-x\\Then:\\\dfrac12x-3=-x\\\dfrac12x+x=3\\\dfrac32x=3\\3x=6\\x=2

Recall: y=-x

Therefore: y= -2

Therefore, a solution to the system of equations is (2, -2)
