Answer:
False, true
Step-by-step explanation:
A str. line on a coord. plane does NOT always represent a function. The vertical line x = 6, for example, represents a case in which there are more than one y-values for each x value. FALSE.
y = 2x + 1 represents a function. For any input, x, the equation y = 2x + 1 returns exactly one y value. TRUE
