We will use the formula for the slope:
m = ( y2- y1 ) / ( x2 - x1 )
For PQ : m = ( 0 - 0 ) / ( a + c - 0 ) = 0
For RS : m = ( b - b ) / ( a - ( 2a + c )) = 0
Both slopes are m = 0, so PQ and RS are parallel to x - axis and at the same time parallel to each other ( PQ | | RS ). One pair of opposite sides is parallel.
Answer:
The options doesn't match or the question is wrong but the answer is (1,2.5)
Step-by-step explanation:

9/100 = 0.09.
it depends on your denominator
Step 1. Divide denominator to numerator .
Step 2. you should have 5.4
Step 3. Keep the denominater (5) and add 5.4 as your numerator. <span />
