Answer:
The weight in pounds is always 2.2 times the weight in kilograms.
Step-by-step explanation:
It was given that two points that are on the graph of a line relating kilograms to pounds are (0,0) and (4, 8.8), where the value of x is the weight in kilograms and the value of y is the approximate weight in pounds.
Based on the options, we need to determine the unit rate and interprete it.
We use the slope formula:
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
We plug in the points to get:
[tex]m = \frac{8.8-0}{4-0}[/tex]
[tex]m = \frac{8.8}{4} [/tex]
[tex]m = 2.2[/tex]
So the proportional relation is
[tex]y = 2.2x[/tex]
This means that the weight in pounds is always 2.2 times the weight in kilograms.
