The graph shows the number of public service announcements that a radio station played throughout the day. Public Service Announcements (PSAs) Aired

A graph has hours on the x-axis, and number of P S A's on the y-axis. A line goes through (1, 4) and (2, 8).

Which equation can be used to represent the number of public service announcements, y, in x hours?
y = StartFraction x Over 4 EndFraction
y = 4
y = 4 x
y = x + 4

Rearrange the formula c^2 = a^2 + b^2 for b

The data in the table represent the height of an object over time. which model best represents the data? height of an object time (seconds) height (feet) 05 1 50 2 70 3 48 quadratic, because the height of the object increases or decreases with a multiplicative rate of change quadratic, because the height increases and then decreases exponential, because the height of the object increases or decreases with a multiplicative rate of change exponential, because the height increases and then decreases
