The values of x used to find point for graphing the line y c

The values of x used to find point for graphing the line y cap = 15.8 + 0.6x are arbitrary. Suppose you choose to uses x = 17 and x = 45. what are the corresponding y cap values (Give your answers correct to one decimal place.) y cap = (x = 17) y cap (x = 45) Are these points on the Iine of best fit Explain why not. No, they do not satisfy the criteria for the Iine of best fit. No, the line of best at is made up of all the points that are in a data set. Yes, because they are reasonable values. Yes, the Iine of best fit is made up of all points that satisfy its equation.

Solution

a)
Given eqn Y = 15.8 + 0.62*x
when x = 17
   Y = 15.8 + 0.62*(17) = 26.34
   x = 45
   Y = 15.8 + 0.62*(45) = 43.7
b)
Yes, the line of fit made up all the points that satisfy this equation

Because the poins look more realistic, with points scattered on the line are best fit
