A parallelogram should have 2 sets of parallel lines. Let's find the slope of line PQ and RS to test.
PQ:
(4-2)/(1-(-3))
2/4
1/2
RS:
(2-0)/(3-1)
2/2
1
Because 1 does not equal 1/2 (the slopes are different) the lines are not parallel. Thus, the figure is not a parallelogram.

Answer:
10, because 10-3 is 7, and 7 is greater than 6.
A will be 7 x 5
B will be 10x10
Answer:
<em>6</em>
Step-by-step explanation:
There are 2 options for 3 items.
So multiple 2 by 3, and you can have a range of 6 lunches able to be chosen.
2 x 3 = 6
