A T-shirt design company charges your team an initial fee of $25 to create the team's design. Each t-shirt printed with your design costs an additional $8. The equation for this situation is 8x + 25. Interpret the y-intercept in context.

The local service center advertises that it charges a flat fee of $50 plus $8 per mile to tow a vehicle. Write an expression that represents the of a service for m miles of towing.

What would be the "a" value (initial value) for this problem?

A local zoo has a population of 32 meerkats. They are doubling every 5 years. How many would there be in 10 years?

What would be the "b" value (multiplier) for this problem?

A local zoo has a population of 32 meerkats. They are doubling every 5 years. How many would there be in 10 years?

The value of a car is $15,000 and depreciates at a rate of 8% per year. What is the exponential expression?

Hint: rise/run

What is the y intercept ?

What is the equation for this line?

The table shows the x and y values for the equation

y = 9x - 1.

Find the missing y value.

The table shows the x and y values for the equation

y = 2x + 1.

Find the missing y value.

Match the equation to the correct graph:

 $y=6x+4$  

Match the equation to the correct graph:

 $y=-\frac{1}{2}x+7$  

Match the equation to the correct graph:

 $y=-8x+5$  

Match the equation to the graph.

 $y=\frac{1}{5}x+4$  

Match the equation to the graph:

 $y\ =\ -\frac{1}{3}x\ +\ 3$  

Convert the equation from Standard Form to Slope-Intercept Form:

 $x+y=-5$  

Convert the equation from Standard Form to Slope-Intercept Form:

 $10x+y=7$  

Convert to Slope-Intercept Form then match the equation to the correct graph.

 $2x+9y=-18$  

Convert to Slope-Intercept Form then match the equation to the correct graph.

 $3x-7y=-21$  

Convert to Slope-Intercept Form then match the equation to the correct graph.

 $3x-4y=24$
