Answer:
y = 1/2 - 3/2
Step-by-step explanation:
All we need to do is find the y-intercept of the line using the formula for slope intercept form [ y = mx + b ].
-3 = 1/2(-3) + b
-3 = -1.5 + b
-1.5 = b
We can put all the information we know/solved for into the formula.
y = 1/2 - 1.5
Best of Luck!

420 = 100*price - (fixed costs)
220 = 60*price - (fixed costs)
If we subtract one from the other one, we get 200 = 40*price, price = 5
that said, fixed costs are 500 - 420 = 80
Now if we move -220 to the right in Answer A, we'll get:
y = 5x -300 + 220 = 5x - 80
So it looks like A describes the model best
Average rate of change of the function: 
Step-by-step explanation:
The average rate of change of a function f(x) can be calculated as:
where:
are the x-values of the interval taken into account to evaluate the rate of change of the function
are the values of the function at those points
In this problem, we have:
The function is 
, so
So, the average rate of change in this interval is:
