Question

About 8 million tons of plastic waste enters the world’s oceans every year. Write a y = mx equation to show this

Answer 1

Answer: $y=8x$

Step-by-step explanation:

For this exercise it is important to remember that the equation of a line that passes through the origin (this is located at the point $(0,0)$), has the following form:

$y=mx$

Where "m" is the slope of the line.

In this case, according to the information given in the exercise, you know that 8 million tons of plastic waste enters the world’s oceans every year, apprdoximately.

Then, let the independent variable "x" represents the number of years.

 Analizing the data given, you can identify that the slope of that line is the following:

$m=8$

So, knowing the value of "m", you can subsitute them into the equation  $y=mx$, in order to get the equation that shows that situation.

This is:

$y=8x$
