Answer:
Line y = -x + 2 intersects line y = 3x + 1
Step-by-step explanation:
The solution to a system of equations is the point at which the two lines intersect. To find this point, first equate the equations and solve for x:
Substitute the found value of x into one of the equations, and solve for y:
Therefore, the solution to the system of equations (the point at which the two lines intersect) is:
So the description that best describes the solution to the system of equations is:
Line y = -x + 2 intersects line y = 3x + 1
