Jimbo Jones spent $46.50 on 3 T-shirts. The next time hespent $31.00 on two T-shirts. What is the cost for one T-shirt?

$15.50

12

State the slope and y-intercept for each equation:

Y = 5x – 1 y = 0.3x 3x + y = 6

Slope = 5

Y-int. = -1

Slope = 0.3

Y-int. = 0

Slope = -3

Y-int. = 6

13

Write an equation in slope-interceptform for the graph shown:

𝒚=𝟓𝟐𝒙−𝟒

14

State the x-intercept and y-intercept of the graph below:

X-int. = 6

Y-int. = -9

15

State the x- and y-intercepts of the equation: 5x + 4y = -20, AND sketch the graph using the intercepts

x-int. = -4 y-int. = -5

16

Monty has a total of $290 in ten and five dollar bills. This can be represented by the function 10x + 5y = 290. Interpret the x- and y-intercepts.

The x-intercept of 29 represents the number of $10 billsThere would be if there were zero $5 bills.

The y-intercept of 58 represents the number of $5 billsThere would be if there were zero $10 bills.

17

Solve the system of equations by graphing:

(-2, -2)
