# How do you solve x+y= -6, y=3x+10 by graphing?

Graph both lines, look for the intersection. They meet at $\left(- 4 , - 2\right)$.
You want both equations in $y = m x + b$ format so they're easier to graph. You can either put them in your calculator or sketch the graphs by looking at the slopes and intercepts in the equation.
For $x + y = - 6$, subtract x from both sides to get $y = - x - 6$. Your y-intercept is -6, and the slope is -1. Graph both lines on the same plane, and look to see where they meet. Here are the lines, and they meet at $\left(- 4 , - 2\right)$.
