The answer should be 10, double check though.
Answer:
$1.21 a pound
Step-by-step explanation:
you have to divide, 30.25÷25= $1.21 per pound
The answer would be 19 because you take the highest number (23) and subtract the smallest number (4) which would equal 19.
So, we are given the y intercept, and since we know c is the same as the y value of the y intercept, we know that c=15.
From there we can pick any two of the points given to us to find our a and b.
Let's use (4,17) and (8,23) becase they are whole numbers.

So, with b=0, we can plug it back into the first equation to get:
So our quadratic is 
Answer:
y = 1/4x + 3
Step-by-step explanation:
m = 1/4, (-4,2)
y -2 = 1/4(x - - 4)
y - 2 = 1/4 (x + 4)
y - 2 = 1/4x + 1
y = 1/4x + 1 + 2
y = 1/4x + 3
