Find and graph 3 points for each equation. $\underline{\ x\ \ \ \ \ \ \ \ \ \ \ \ 3x\ \ \ \ \ \ \ \ \ \ \ \ \ y\ \ }$ $-1\ \ \ \ \ \ \ 3(-1)\ \ \ \ \ -3$ $\ \ \ 0\ \ \ \ \ \ \ \ \ 3(2)\ \ \ \ \ \ \ \ \ \ \ \ 6$ $\ \ \ 1\ \ \ \ \ \ \ \ \ 3(1)\ \ \ \ \ \ \ \ \ \ \ \ 3$ $\underline{\ x\ \ \ \ \ \ \ \ \ \ \ \ x+4\ \ \ \ \ \ \ \ \ \ y}$ $-6\ \ \ \ \ -6+4\ \ \ \ \ -2$ $-2\ \ \ \ \ -2+4\ \ \ \ \ \ \ \ \ \ 2$ $\ \ \ 1\ \ \ \ \ \ \ \ \ \ 1+4\ \ \ \ \ \ \ \ \ \ 5$ The lines intersect where x=2 and y=6. When x=2, 3x=6. When x=2, x+4=6.
