The value (y2) of r = 1/2.
This question relates to equation of a straight line but we are looking for the slope in this case.
<h3>Slope</h3>
This is the ratio to which we measure the change along the y-axis to the change along the x-axis. The formula is given as

Data given;
- x1  = 3
- x2 = -3
- y1 = 5 
- y2 = r
- m = 34 or 3/4
Substitute the values into the equation and solve for the unknown
NB; we are assuming that the slope here is 34 and not 3/4.

cross multiply both sides and make r the subject of formula

the value of r = -199. 
This is not mathematically obtainable and we would use 3/4 as the value of slope

The most logical value of r = 1/2
