2. Larry has an image that is 12 inches tall and 16
inches wide. If he wants to reduce the image
proportionally to fit on an 8-inch-by-10-inch sheet of
photo paper, what is the maximum size the reduced
figure could be?
Maximum = Largest
Proportionally means to set up

13.3 in. is larger than 10 in.
Possible answer, but not the maximum
12/16 ≠ 6/9 so they are not proportional
Correct Answer!
3. If ABCD is translated so that B(3, 5) is
mapped to point B’(1, -1), which ordered pair
represents either A’ or D’? Translate means to slide

Correct Answer!
Count spaces from B to B’. (1, -1) is not a translation rule, it is a point.

represent?
With inequalities, make sure to check:
y-intercept,

Wrong y-intercept and slope.
Wrong slope, wrong type of line.
Correct Answer!
Wrong type of line, incorrect shade.
5. A basketball has a diameter of 8 inches.
What is the closest to the volume?
A basketball is technically a sphere.
