The solution of the system is $(-4,-7)$

We are given $y=2x+1$ The slope is $2$. The y-intercept is $1$ $y=x-3$ The slope is $1$. The y-intercept is $-3$ We can see from the graph that the solution of the system is $(-4,-7)$. Check to see if $(-4,-7)$ makes both equations true. $-7=2(-4)+1$ $-7=-7$ $-7=-4-3$ $-7=-7$
