1. Which equation has a graph parallel to the graph of 9x + 3y = –22 ? (1 point) y = 3x – 22
y = –3x + 8
y = x + 12
y = – x – 2
2. Which equation has a graph perpendicular to the graph of 7x = 14y – 8 ? (1 point)
y = –2x – 7
y = – x + 4
y = x + 1
y = 2x + 9
3. Which equation is the equation of a line that passes through (–10, 3) and is perpendicular to y = 5x – 7? (1 point)
y = 5x + 53
y = – x – 7
y = – x + 1
y = x + 5
4. Which of the following coordinates for P will make line MN perpendicular to line OP in the diagram
below?
(1 point)
(–2, –5)
(–3, 6)
(3, 2)
(3, 5)
5. Segment XY represents the path of an airplane that passes through the coordinates (2, 1) and (4, 5). What
is the slope of a line that represents the path of another airplane that is traveling parallel to the first
airplane?
(1 point)
–2
2
-1/2
1/2

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.

a.) list the factors of 40.

1/2/4/5/8/10/20/40

b.) list the factors of 40 that represent the number of cans that could be on each shelf.

5

c.) how many different arrangements of cans are possible?

just one because if you put more on one shelf you will go way over 40 and the cabinet will probably break.

d.) what are the possible arrangements of the cans?

put 5 cans on each self to reach 40 cans in total.

e.) which arrangement uses all the shelves?

5 because you can put 5 cans on each shelf, and since there are 8 shelfs you are equally going to get 40 cans.
