Aproportional relationship is shown in the table below:
xxx 000 111 222 333 444
yyy 000 333 666 999 121212
what is the slope of the line that represents this relationship?
\qquadspace

graph the line that represents this relationship.

The slope is

Step-by-step explanation:

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

Let

------> from the given table

Find the value of k

substitute the values

The linear equation is

using a graphing tool

see the attached figure

The slope of a proportional relationship is the rate of change of the relationship

The slope of the relationship is 3

Pick any two points from the table;

The slope (m) is calculated as:

So, we have:

Subtract

Divide

Hence, the slope of the relationship is 3

Because it is a proportional relationship, the equation of its graph is:

Substitute 3 for m

See attachment for the graph of
