Answer:
y= -4x + 5
Step-by-step explanation:
Use the point slope formula:
y-=m(x-
)
We know the slope, or m, is -4. This is because parallel lines have the same slope
Substitute -4 in for m, -15 in for , and 5 in for
y--15=-4(x-5)
Distribute the -4
y+15= -4*x+-4*-5
y+15= -4x + 20
Subtract 15 from both sides
y= -4x +5
Hope this helps! :)

Answer:
a.
b. 17 years
c. The amount that is currently charged by the college you attend is much higher than the amount charged in two-year college in the present year.
Step-by-step explanation:
a.
Here, x is a the number of years after 2000 and f(x) is the total cost.
To approximate the yearly cost of attending a two-year college in the year 2016, find .
b.
To predict in what year the yearly cost of tuition and required fees will exceed $3200, solve
So,
x is approximately equal to 17 years.
c.
The present year is 2020.
To approximate the yearly cost of attending a two-year college in the present year, find
The amount that is currently charged by the college you attend is much higher than the amount charged in two-year college in the present year.
