Function A and Function B are linear functions.
Function A
y = ½x − 2
Function B
[Graph of a line passing through (0, 2) and (10, 6).]
Which statement is true?
The y-value of Function A when x = 10 is greater than the y-value of Function B when x = 10.
The y-value of Function A when x = 10 is less than the y-value of Function B when x = 10.

Answer

The second statement is true: The y-value of Function A when x = 10 is less than the y-value of Function B when x = 10.

Function A: y = ½(10) − 2 = 3. From the graph, Function B has y = 6 when x = 10. Since 3 < 6, Function A has the smaller y-value.
