A(0,0),B(5,8) and C(10,4)
What is the ratio of the slope of AB to the slope of AC


the slope of AB
Solved by pluggable solver: Finding the slope


Slope of the line through the points (0, 0) and (5, 8)



Answer: Slope is m+=+8%2F5



the slope of AC
Solved by pluggable solver: Finding the slope


Slope of the line through the points (0, 0) and (10, 4)



Answer: Slope is m+=+2%2F5



the ratio is: m=8%2F5 m1=2%2F5
-> m%2Fm1=%288%2F5%29%2F%282%2F5%29
m%2Fm1=%288%2A5%29%2F%285%2A2%29
m%2Fm1=%28cross%288%294%2Across%285%29%29%2F%28Cross%285%29%2Across%282%29%29

m%2Fm1=4..............(E)4
