What is the ratio of the AREA (YOU must calculate the area) in square miles of the campus to the area in square feet of the map?
1:2
4:1
1:4

1.5 cookies
4.5 cookies
Use the coordinate plane to help find the correct answer.
Do the points in this set form a proportional relationship?
Point 1: (-3,-9)
Point 2: (1, -1)
Point 3: (3, 3)
Point 4: (6, 9)
Yes, because the line connecting the points is a straight line
No, because the line connecting the points does not pass through the origin.
No, because the line connecting the points is not a straight line.
A series of triangles all have the same height but different bases. The table below shows the length of the bases and the area of each triangle.
Examine this table to decide whether or not the quantities in the two columns are proportional.
Base = 3, Area = 4.5 sq in
Base = 5, Area = 7.5 sq in
Base= 10, Area = 15 sq in
Base = 15, Area = 22.5 sq in
No because 10 and 15 are not proportional to the others.
Yes, because 1.5 times the bases always gives the area.
Yes, because the area is always twice the base.
The coordinate plane below shows the graph of line m. The line passes through the origin and point (3,2).

The graph below represents the amount of paint Mrs. Abel used when she painted four rectangular walls that have the same area.
the graph is not a straight line through the origin because the proportion of paint per wall is the same for each wall.
the graph is a straight line through the origin because the proportion of paint per wall is the same for each wall
The graph is not a straight line throuh the origin because the proportion of paint per wall is not the same per wall.
Alex sells news papers to his customers for $0.50 each and makes a profit of $0.15 for each paper he sells. If p represents total provit and C represents the number of copies he sells, which equation correctly shows the amount of profit he makes?
P = 0.50 C
C = 0.15 P
P = 0.15 C
Which equation represents the relationship between x and y in the table?
x ⋅ y = 3.2
y = x3.2
y = 3.2 x
For a science project, Beatrice studied the relationship between H, the height of a corn plant, and d, the number of days the plant grew. She found the relationship to be proportional. Which equation models a proportional relationship between H and d?
H = 1.5 + d
H = d1.5
H = 1.5 - d
H = 1.5 d
The time it takes Sam's computer to download a music file is proportional to the size of the file. A 6-megabyte file takes 10 seconds to download. Which equation describes the relationship between x, the file size in megabytes and y, the time in seconds?
y = 5/3 x
y = x + 4
y = x - 4
