1. for the data in the table, does y vary directly with x? if it does write an equation for the direct variation.

10 | 12
15 | 18
20 | 24

A. yes; y = 1.2x
B. yes; y = 2x
C. yes; y = x + 1
D. no; y does not vary directly with x

2. For the data in the table, does y vary directly with x? if it does, write an equation for the direct variation.

x | y
32 | 24
16 | 8
8 | 6


3. Match the equation with the graph. y=1/3x-6

4. Match the equation with the graph. -3x+5y=15

5. The table shows the number of miles driven over time.

time (hours) | distance (miles)
4 | 204
6 | 306
8 | 408
10 | 510

6. Fine the slop of the line. So I can't put the picture in but I can put the answers in and hopefully someone will know what the graph looks like or has taken the test and knows the answer lol.
A. -4
B. -1/4
C. 1/4
D. 4

7. what is the slope of the line that passes through the pair of points (3,8) and (9,5)

8. What is the slope of the line. Again I can't put the picture in so ill just put the answers.
A. 0
B. 1
C. undefined
D. infinity

9. write an equation in point-slope form for the line through the given point with the given slope. (8,3); m=6

10. write an equation in point slope form for the line through the given point with the given slope. (-10, -6); m=-5/8

11. The table shows the height of a plant as it grows. Which equations in point slope form gives the plants height at any time

time (months) | Plant height (cm)
2 | 18
4 | 36
6 | 54
8 | 72

12. what is the graph of the equation. x=-5

13. write y=-3/4x+3 in standard from using integers.

14. write an equation for the line that is parallel to the given line and passes through the given point. y=5x+10; (2,14)

15. tell whether the lines for each pair of equations are parallel, perpendicular, or neither
y=-3x+7

-2x+6y=3

16. tell whether the lines for each pair of equations are parallel, perpendicular, or neither
y=-1/4x+10

-2x+8y=6

17. write the equation of a line that is perpendicular to the given line and that passes through the given point.
y-2 =7/3(x+5); (-4,9)

18. below are functions of y=|x| and y=|x|-5. How are the functions related

19. describe how the graphs of y=|x| and y=|x+2| are related

20. graph y=|x|-5

21. graph y=|x-4|

22. which type of correction is suggest by the scatter plot.

So I didn't add the answers only cause I'm lazy af. But if anyone needs me too I can.
