x–2–101 y Write an equation in slope intercept form to represent the relationship shown in the table y = 2x + 8

3. What is the equation for a line passing through the points (–4, –4) and (1, 6)?

y = -x + 2

+7 +1 m = 7 b = -2

7. Parallel lines have the same slope. What is the slope of a line parallel to 8y = 32x + 8? Record your answer and fill in the grid. Be sure to use the correct place value.

8. The teacher spent $ on supplies. He bought expo markers for $107.90, pencils for $95.45, and some notebooks for $4.75 each. How many notebooks did he buy?

9. An online sports ticket selling company charges a service charge of $5 to buy tickets. Each ticket costs $62 for a basketball game. Write an equation to represent the cost of buying tickets through the company.

10. Find the values of x and y that simultaneously satisfy the two equations by graphing. y = -2x - 8 and y = x + 4 (-4, 0)

+6 +3

13. The number of nickels in a coin collection is 6 less than 4 times the number of dimes. If x represents the number of dimes, which equation represents the relationship between the number of nickels and number of dimes in the collection?

19. Joel is charged $25 at the car wash for the deluxe wash. He leaves a 5 dollar tip. What percent tip did he leave?

20. Which statement is true about the non-proportional linear relationship defined by y = 6x + 10? F The graph is a line containing the point (10, 0). G The table of values for the relationship could contain x = −2 and y = −2. H The graph is a line with a slope of 10. J The graph is a line with a y-intercept of 6. F 0 = 6(10) = 70 G -2 = 6(-2) = -2 H y = 6x + 10 J y = 6x + 10
