Solution:

The coordinates (-6, 4) satisfy the equation:


y=(1)/(3)x+6

because


\begin{gathered} when\text{ x = -6, we have} \\ y=(1)/(3)(-6)+6=-2+6 \\ \Rightarrow y=4 \\ (-6,\text{ 4\rparen is on the graph of y=}(1)/(3)x+6 \end{gathered}

If (-6, 4) satisfies the equations of two lines, (-6, 4) is


on\text{ both lines}

so that the lines will


intersect

at (-6, 4).

This means that if two lines


intersect

at (-6, 4), then (-6, 4) is the


solution

to the system of equations.

This means that if you substitute -6 for x and 4 for y in the equations, both equation will be


True
