Y = mx + b
m is your slope AKA rate of change
b is the y intercept.
from the graph we can see that the y intercept (b) is 15. (look at the y axis and see what point the line crosses on the y, here it is 15, in-between 10 and 20)
slope is rate of change. to figure this out remember slope = rise over run:

so pick two points. how much does one point rise after the other point you picked? In the graph it rises 1 square so rise = 1
Now looking at the same two points, how far away from each other are they on the x axis? Looking at the graph they are 2 squares away from each other. so run = 2
Now plug these numbers into the rise over run formula:

Now we have everything we need to put into our formula for a line:


For number 16 you should get:

Answer:
This is not a solvable question, since the least amount of money you can have with this combination is $4.20.
Step-by-step explanation:
Let q = quarters
Let d = dimes
Equation: 0.1d + 0.25q = 3.00
Maximum amount of dimes: 0.1d *42 = 4.2d
