Which statement best explains if the graph correctly represents the proportional relationship y = 3.5x? a graph of a coordinate plane is shown. points are graphed at 1 and 3.5 and 2 and 7. the points are joined by a line. it does, the points shown on the line would be part of y = 3.5x. it does not, proportions cannot be represented on a graph. it does not, the points shown on the line would not be part of y = 3.5x. it does, all proportions can be shown on the graph of this line.

It does, the points shown on the line would be part of

Step-by-step explanation:

see the attached figure to better understand the problem  

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

In this problem we have

The slope is equal to ------> is a positive slope

The line passes through the origin

therefore

This linear equation represent a proportional variation

Verify the values of the points of the graph with the equation

For

-----> is correct

For

-----> is correct

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.
