Here is a similar question attached with.
Option (b) that is 2005 is the right choice.
Step-by-step explanation:
Given:
An equation in slope intercept form.
Where = number of years
Comparing from the standard slope intercept form.
y-intercept value
According to the question the predicted winning speed mph
Plugging the value of in slope intercept form, we will calculate the (number of years) and then we will add this with .
⇒
⇒
⇒
⇒
⇒
⇒
Finally the year would be
So in year 2005 the winning speed is predicted to be 7.16 mph.
