Answer 1

B. y = 0.5x + 1.8

Explanation:

Here we have to use table values and find the correct equation.

Look at the scatter plot

Let's take a few points from the table and check.

Let's take equation B.

y = 0.5x + 1.8

Plug in x = 1 and find the y value

y = 0.5(1) + 1.8

y = 2.3

Plug in x =2 and the value of y

y = 0.5(2) + 1.8

y = 1 + 1.8

y = 2.8 which is near to 3

Let's take the last point and check

when x = 10,

y = 0.5(10) + 1.8

= 5 + 1.8

y = 6.8 which more over near to 6.5

Therefore, the answer is B. y = 0.5x + 1.8

Other equations varies a lot in value.

Hope this will helpful to understand.

Thank you.
