Question

Data were collected on the distance a golf ball will travel when hit by a golf club at a certain
speed. The speed, s, is measured in miles per hour, and distance, y, is measured in yards. The
regression line is given by ý = 5.32 + 46.73s.
Identify the slope and y-intercept of the regression line. Interpret each value in context.

Answer 1

Answer:

m=4.46

c=5.32

Step-by-step explanation:

Given that the regression line is described by the expression

ý = 5.32 + 46.73s

we can also write the expression for the equation of a straight line and compare the values.

the expression for a straight line is given as

y=mx+c

where m= slope          

            c= intercept

         

Comparing the equation given with the straight-line equation, we can see that the gradient  m=4.46

and intercept c= 5.32
