Question

X+y=9

y=1/2x

What are the coordinates of the point where the graphs of the two equations intersect?

Answer 1

So right off the bat I noticed that the top equation isnt an actual line equation. To make it one I subtract x from both sides. The outcome equation is y=-x+9.
Next I graph both equations and find the intersection.
The point at which both lines intersect is 6,3
