What makes a graph proportional? Select two answers.

(a)   ​ ​​ (b)  

• straight line through point of origin (0, 0)
• has a constant of proportionality
• a line that connects the dots
• has x-axis and y-axis

A proportional relationship can be written as an equation in the form =  ​ ​

• y = k+x

• y = k/x

• y = kx
