Answer:
PQ and RS are parallel to each other
Step-by-step explanation:
Slope of two points (x1,y1) and (x2,y2) is given by
slope = (y2-y1)/(x2-x1)
- for two lines to be parallel slope should be equal
- for two lines to be perpendicular product of slope should be -1
- _______________________________________________
Lets find the slope of PQ and RS
for PQ P(2, -1), Q(-3,-1), R(-11, 9), S(-7, 9)
slope PQ = (-1 -(-1))/(-3 -2) = (-1 + 1)/5 = 0/5 = 0
Slope RS = (9-9)/(-7 - (-11) ) = 0/4 = 0
Since
slope PQ = slope RS = 0
Hence PQ and RS are parallel to each other

Step-by-step explanation:
Before we begin answering, we need to go over the rules of multiplying polynomials.
Unlike in regular multiplication, we have to combine the like terms in the subtracting portion of the multiplication process.
Another rule is that when there are more than 1 variable in a term, we need to take the variables as two separate variables and then proceed to multiply them.
