1. Bell work:
A park’s revenue for tapes sold is modeled by the function r(x)=9.5x. The cost of producing the tapes is c(x)=0.8x+1940.
Write a function to describe the profit for selling x tapes.

4. Graph 5x+7y-10=0 using the intercepts

5. Find the slope of the equation 3x+2y-7=0

6. Graph the equation y=2x+3

7. Zeroes of a function
A function’s zeroes are the input(s) that produce an output of zero; alternatively, they are points where the functions crosses the x-axis

8. What does a constant function look like?

9. Write 5x+3y-23=0 in slope intercept form
