9. A submarine that is on the ocean floor (500 meters down) and ascends at a rate of 5 meters per
second has an equation that can be written as:
a.
Y = -5x + 500
b. y = 5x + 500
c. y = 5x – 500
d. y = -5x – 500
10. A submarine with an equation of y = -5x descends to rescue a scuba diver who is ascending
towards the ocean surface with an equation of y = 2x – 200. What is their point of intersection?
a.
(28, -142)
b. (66, -330)

11. T-shirt company A charges $4.00 per t-shirt plus an initial fee of $9.00. T-shirt company B has
no initial fee but charges $7.00 per shirt. After how many t-shirts will it be the exact same cost for
company A and company B? In your answer document, write an equation for each company.
Visually represent each company in a graph. Determine the point of intersection. Describe a
situation in which it would be best to go with company A in comparison to company B.

Understand that
solutions to a system
of two linear
equations in two
variables correspond
to points of
intersection of their
graphs, because
points of intersection
satisfy both
equations
simultaneously.
Solve systems of two
linear equations in
two variables
algebraically, and
estimate solutions by
graphing the
equations. Solve
simple cases by
inspection.
Solve real-world and
mathematical
problems leading to
two linear equations
in two variables.
