10. Write a Linear Equation

11. 6. Write an equation in Standard Form of the line with x-intercept 7 and parallel to 6x – 9 = 3y Parallel slope = 2 Point (7, 0) y – 0 = 2(x – 7) y = 2x – 14 2x – y = 14 Get into slope- intercept form 6x – 9 = 3y y = 2x – 3

12. Write an equation in standard form Or you already know the slope and y-intercept y= mx + b y = 3x + 6 3x – y = –6

20. Find the Difference Quotient

21. Function 15. Find domain & range and determine if the relation is a function. {(–1, –2), (–3, 4), (–1, 0)} Domain: {–1, –3} Range: {–2, 0, 4} Not a function because x = –1 twice with different y – values

22. a. Find f ( –3 ) = 3( –3 ) – 7 = – 16 Find Function Values c. Find f ( g ( –3 )) = 3(27) – 7 = 74

23. Find Domain & Range

24. Word Problem 18. The cost (in dollars) of operating a pizza delivery car is given by C = 9000 + 0.5x, where x is the number of miles that the car is driven. Use appropriate restrictions on the variable & graph this equation. Cost (y) won’t go below 0, depends on miles (x), which also won’t go below 0. Graph by finding y – intercept & x – intercept.

25. #18 continued 18. C = 9000 + 0.5x (0, 9000) & (–18000, 0) Don’t have graph on Quadrant II 9000 –18000milesCost

26. Applying Slope 1(y – 2) = 2(2) y – 2 = 4 y = 6
