The graph shows a proportional relationship between the variables Y and X. Explain how you know there is a proportional relationship if you are given either equation or graph.

If the line is straight pointing diagonally to the top right corner then it is a proportinal relationship.

Step-by-step explanation:

if the line is diagonally upwards to the right, then if x increase, y increases, and if x decreases, then y increases.

for an equation, x must be positive. for example

y=-2x is not proportional but y=3x is

for the question in the photo the equation is y=x

is it 35
