Why is a regression line referred to as the line of best fit?
aalyn [17]
<h2>Answer with explanation:</h2>

When there is a linear relationship is observed between the variables, we use  linear regression predict the relationship between them.

Also, we predict the values for dependent variable by modelling a linear model that best fits the data by drawing a line Y=a+bX, where X is the explanatory variable and Y is the dependent variable.

In other words: The line of best fit is a line through a scatter plot of data points that best describes the relationship between them.

That's why the  regression line referred to as the line of best fit.

These triangles are similar. find Y and X
CaHeK987 [17]

It these triangles are similar, then the sides of the triangles are in proportion:

\dfrac{y}{10}=\dfrac{y+4}{15}      <em>cross multiply</em>

15y=10(y+4)    <em>use distributive property</em>

15y=10y+40       <em>subtract 10y from both sides</em>

5y=40           <em>divide both sides by 5</em>

\boxed{y=8}


\dfrac{x}{4}=\dfrac{6}{8}            <em>cross multiply</em>

8x=(4)(6)

8x=24           <em>divide both sides by 8</em>

\boxed{x=3}
