assessment credit checkpoint
complete the following problems. show all your work.
learning goal from lesson 22.5
i can solve a system of equations consisting of a linear equation and a quadratic equation algebraically and graphically.
how i did (circle one)
i got it im still learning it.
use the graph of the systems of equations below to answer questions 1 - 2

1. choose yes or no to indicate which of the ordered pairs given is a point of intersection and solution to the system above. (1/2 point)

ordered pair yes no
(-2, 4)
(3, 2)
(-5, -4)
(4, 10)

Explanation:

Step1: Check (-2, 4)

Locate x = - 2 on the x - axis and y = 4 on the y - axis. See if the point lies on both graphs. It does, so it's a solution.

Step2: Check (3, 2)

Locate x = 3 and y = 2. The point does not lie on both graphs, so it's not a solution.

Step3: Check (-5, -4)

Locate x=-5 and y = - 4. The point does not lie on both graphs, so it's not a solution.

Step4: Check (4, 10)

Locate x = 4 and y = 10. The point lies on both graphs, so it's a solution.

Answer:

(-2, 4): Yes
(3, 2): No
(-5, -4): No
(4, 10): Yes
