U have to check these: (proportional) 1. Does it pass through (0,0)? 2. Is the equation for the graph is y=kx ? For example: y= 3x • if the simplified ratio of y/x are equal then they are proportional
Not proportional: 1. Does NOT pass through (0,0) 2. Equation format is y=mx+b For example : y=3x+11
