The answer cannot be determined from the information provided.

Answer: Option B.

<u>Explanation:</u>

A linear regression line has an equation in the form Y = a + bX, where X stands for the explanatory variable and Y is used to denote the dependent variable in the equation. The slope of the line is b, and a is the intercept (the value of y when x = 0).

A regression line (LSRL - Least Squares Regression Line) is a straight line that explains how a dependent variable y changes as an explanatory variable x changes. The line is a mathematical model used to predict the value of y for a given x. Regression requires that we have an explanatory and response variable.

EPS = (1,000 - 800) / 100

= $2.00

<em>The only option less than $2.00 is the first option of $1.90 so this is correct. </em>
