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
Answer:Therefore, the relationship will be of the form, y = mx + b, or in this case, d = (max distance / max time)t + 0.
Step-by-step explanation:
I think it's true.
Because any number added to 0 is equal to itself.
