Question

A line that goes through the origin and the point (10, 5) what is the slope

Answer 1

Let the line be y= mx+C  

Passes through origin i.e (0,0)  

Hence 0= m×0+C →C=0  

Hence line becomes y= mx  

Passes through origin i.e (10,5)  

Hence 5= m×10→m=5/10= 0.5  

Hence line becomes y=0.5 x
