a line of best fit is drawn for the set of points shown on the graph. which point is an approximate extrapolation for ( x = 30 ) from the line of best fit? ( (23,30) ) ( (30,38) ) ( (44,30) ) ( (30,72) )

a line of best fit is drawn for the set of points shown on the graph. which point is an approximate extrapolation for ( x = 30 ) from the line of best fit? ( (23,30) ) ( (30,38) ) ( (44,30) ) ( (30,72) )

Answer

Explanation:

Step1: Recall the formula of the line of best fit

The formula of the line of best fit is (y = 1.14x+3.805).

Step2: Substitute (x = 30) into the formula

When (x = 30), we calculate (y) as follows: [ \begin{align*} y&=1.14\times30 + 3.805\ &=34.2+3.805\ &=38.005\approx38 \end{align*} ]

Answer:

((30,38))
