If each case weighs 24 pounds, then 1p=24 pounds. so if we're trying to find a function of weight, p=24c.
Example: When you have 2 cases, you plug in a 2 for c
p=24c
p=24(2)
p=48
So if you have two cases, it will total 48 pounds,
So that is why the equation is p=24c. Hope this helps!
The answer is D: An account earning interest compounded daily.
You have to set it up as two problems then combined like terms then add them together
y = mx + b
To find the slope(m), you use the slope formula:

You plug in the points into the equation.


The slope is 0
y = 0x + b
Any number multiplied by 0 is 0. So:
y = b
To find b, you plug in the y value of either of the points.
-4 = b
Your equation is:
y = -4 (This is a horizontal line)
