Information
Correct !
The line you have graphed perfectly matches the first equation!
Now try to graph the second equation on the same coordinate plane.
+1 POINT
The line you have graphed perfectly matches the second equation!
+1 POINT
Finally, for two more points, can you solve the system of equations?
The line you have graphed does not match the first equation.
Check your solutions carefully and try again.
