CCSS.HSA.REI.C.6

What is the solution to the system?

• (0, 3)

• (1, -1)

• (-3, 1)

• (1, 3)

Answer explanation

The lines intersect at (1,3) so that is the solution.

Will the solution (-3, -7) make the following system of equations a true statement? y = 4x + 5 y = x – 4

• YES

• NO

Answer explanation

The equations are exactly the same. (SAME slope AND SAME y-intercept). The lines intersect at EVERY point.​ ​

• Infinitely Many Solutions

• No Solution

• One Solution
