$(4,2)$

Work Step by Step

Please see the screenshot of the tables for the two equations. Purple line: $y=2$ Green line: $2x-y=6$ If we replace $x$ and $y$ with $4$ and $2$, respectively, for the green line, we have $2x-y=6$ $2*4-2=6$ $8-2=6$ (true) Purple line: $y=2$ $2=2$ (true) Purple line: $m=0$, y-intercept is 2 Green line: $m=2$, y-intercept is -6
