Question 21 • LHS Algebra I

Graph the function y = |8 - 2x| + 3. Which is a point on the function?

Answer
A
(6.2, 7.4)
B
(7.8, 11.2)
C
(8.6, 6.8)
D
(9.6, 7.3)

Explanation

Substitute the x-coordinate of choice A, 6.2, into the function: y = |8 − 2(6.2)| + 3 = |−4.4| + 3 = 7.4. This matches the point’s y-coordinate, so (6.2, 7.4) is on the function.
