To compute the slope of a segment, given its endpoints
, you write

Given this formula, you have the four slopes:




Now, two segments are parallel if they have the same slope. So, AB and CD are parallel, because they both have slope 1, but BC and DA are not parallel.
This means that ABCD is not a parallelogram, because in parallelograms the opposite sides are parallel.
Well, first, you need to add up the amount of ten fridges and ten pianos. than you see if its heavier or lighter... > or <....... do you remember how to graph?
10/16 are blue and red marbles, simplifying to 5/8
