Question

Describe a situation that is defined by the linear equation P = 40 + 22t.

The initial amount is 40 and the rate of change is 62.
The initial amount is 62 and the rate of change is 22.
The initial amount is 22 and the rate of change is 40.
The initial amount is 40 and the rate of change is 22.

Answer 1

Hint:
In the linear equation, y=mx+b
the initial value is b, and
the slope (or rate of change) is m.
The slope is the coefficient of the independent variable x.
The initial value is a constant.

Answer 2

This equation is basically y=mx+b
In order to match this equation to y-mx+b, we can change the given equation to y=22x+40
b is always a starting value so 40 is the initial amount.
mx is the slope of how many you go up or down to get to the next value.
In this cause, that is the rate of change, it it must be 22.
The answer should be the last one.
