Example
Paolo is going to take part in a 20-kilometer walk.
He makes this graph to show the relationship
between time and remaining distance if he
maintains his planned speed. Write an equation
for this function.
Make a table to

find the slope and
y 2016 12 8 40
the y-intercept.
Distance
Remaining (km)

Time (hr)
The table shows that when x = 0, y = 20, so the y-intercept is
20. As each x-coordinate increases by 1, each y-coordinate
decreases by 4, so the slope is 4, or-4.
The equation is y = - 4x + 20.

1 What do the y-intercept and the slope mean in the
context of the example problem?

Asample of 200 rom computer chips was selected on each of 30 consecutive days, and the number of nonconforming chips on each day was as follows: the data has been given so that it can be copied into r as a vector. non.conforming = c(10, 15, 21, 19, 34, 16, 5, 24, 8, 21, 32, 14, 14, 19, 18, 20, 12, 23, 10, 19, 20, 18, 13, 26, 33, 14, 12, 21, 12, 27) #construct a p chart by using the following code. you will need to enter your values for pbar, lcl and ucl. pbar = lcl = ucl = plot(non.conforming/200, ylim = c(0,.5)) abline(h = pbar, lty = 2) abline(h = lcl, lty = 3) abline(h = ucl, lty = 3)
