Explain how you can use a table of values, an equation, and a graph to determine whether a function represents a proportional relationship.

From the table: you have to have the same increment for the x values and the same increment for the y values. Doesn't have to be the same increment for both x and y values.

From an equation: the exponent of the x and y should be 1. The equation should be a line equation.

From a graph: the graph should be a continuous straight line.

Step-by-step explanation:

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !

step-by-step explanation:

x=6 and x=3
