Question

Robert earns $88 in interest each year. Which graph shows the relationship between the number of years that pass and the amount of money he earns in interest?

Answer 1

I plugged the equation into Desmos and the graphs are below.

Explanation:

If the graph is supposed to be a line instead of points, then the graph should look like the first picture.

If the graph is supposed to show just the points instead of a line, then the graph should look like the second picture.

If none of your choices look similar to those look for an image that has these points.

Interest | years

88 | 1

176 | 2

264 | 3

352 | 4

If you need more points, all you have to do is multiply 88 by however many years. For example if it's been 16 years and you need to know how much interest he's collected in that time you do 88 x 16 to find your answer.
