Question

The scatterplot above shows the number of registered voters, , x and the number of people who voted in

the last election, y , for seven districts in a town. A line of best fit for the data is also shown. Which of the following could be the equation of the line of best fit?

- y = 2x

Hint:

**Hint:**

- Equation of straight line can be written as

## The correct answer is:

### Explanation:

- We have given a plot of the number of registered voters, x, and the number of people who voted in the last election, y, for seven districts in a town.
- We have to find the equation of the line in the plot.

Step 1 of 1:

The given plot is

We take two points on from the graph and then write the equation.

So,

Two points are

Since this is a straight line, we will write equation using point slope form.

So, The equation will be

Hence, Option B is correct.
