What is least common multiple of 4.8 and 18 is 8
we can mark points on the graph shown , check the image I have shared with this for the points .
Formula for slope = 
So for Line A points are (1,3) and (0,-1)
So using t he formula slope is = 
slope of line A =4
For Line B the points are (0,4) and (3,-5)
So using t he formula slope is = 
slope of line B = -3
