Answer:
1/4
Step-by-step explanation:
Slope of a line can be found if given two points by using the formula 
where 
are points on the line.
However, I like to line up the points vertically and subtract then put 2nd difference over 1st difference.
Like this:
( 3 , 3 )
-( -1 , 2 )
---------------------
4 1
So the slope is 1/4.
Answer:

Answer:
RQ = 9.
Step-by-step explanation:
m < RPQ = 180 - 90 - 75 = 15 degrees
m < PQM = 75 - 60 = 15 degrees.
So triangle PMQ is isosceles so side PM is congruent to side MQ, therefore MQ = 18.
Triangle RQM is a 30-60-90 triangle with RQ the shortest leg (because it is opposite the lowest angle) so that makes RQ = 1/2 of MQ. (The sides in a 30-60-90 triangle are in the ratio 1:sqrt3:2)
RQ = 1/2 * 18 = 9.
