The linear equation that describes the number of miles Emma rides, y , in terms of the number of minutes, x , she rides is y = 3x

How to determine the linear equation that describes the situation

From the question, we have the following parameters that can be used in our computation:

Time (hours) Miles

1 3

2 6

4 12

6 18

From the above, we can see that

As x increases by 1, the value of y increases by 3

This means that the slope of the relation is 3

A linear relation is represented as

y = mx + c

So, we have

y = 3x + c

Using the points on the table, we have

6 = 3 * 2 + c

c = 0

So, we have

y = 3x

Hence, the linear equation is y = 3x
