The slope is:  m= (Ysub2 - Ysub1) / (Xsub2 - Xsub1), where m is the slope and Xsub1 is not equal to Xsub2. 
 
Let the first ordered pair (-3, -10) be called (Xsub1, Ysub1) and the second ordered pair (4, 5) be called (Xsub2, Ysub2). 
 
Substituting the values for the slope,we have  
 
m = [5-(-10)] / [4-(-3)] 
 
m = (5+10) / (4+3) 
 
Therefore the slope of the line m = 15/7.
