16. passes through (-4,7) and (-9,-1)
17. x-intercept = 5 and y-intercept = -4.
18. slope = 3/4,x-intercept = -3
19. passes through (1,4) and is perpendicular to a line whose
equation
is y = 3x + 5.
20. passes through (1,4) and is parallel to the line whose
equation is
y = 3x + 5
Use the information in the table to solve the following
problems.
The table shows the relationship between the phone calls made
and
tickets sold during a fund-raising campaign by eight
callers.
21. Using your calculator, find a prediction equation to show
how the
tickets sold are related to the number of calls made.
22. Predict the number of tickets that could be sold if a caller
made 50
calls.. (Round using the greatest integer concept)
23. How many tickets are being sold per call?
