Module 12 Intro
The line we will use to describe this
scatterplot is:
D = -3A + 576
where A is age of the driver, and D is the
distance (in feet) they can read the sign.
1. Using the linear equation above, find the predicted max distance each age can read:
 Age 57
 Age 8
2. When can we not predict? ____________________________________________________
3. What is the slope? _________ Interpret the meaning of the slope in context to the problem.
4. What is the y- intercept? ______________ Interpret the meaning of the y-intercept in context
to the problem. Does it have meaning here?
5. Does the older you get, the further you can read?
6. For every year you get older, how much less can we predict you will be able to read?
7. Can we make a prediction for Betty, if she is 93 year old?
