Helpful Test Review!

You guys have been doing a great job posting.  As a gift, I have supplied a few helpful review problems for tomorrow's test.  Some of these questions might even show up!




Find the line parallel to y = 3x + 4 that contains the point (-1, 5)
Graph both lines.


Find the line perpendicular to 4x - 3y =12 that contains the point (8, 2).  Graph both lines.

Find the slope of the line that passes through the given points.

 (1, 3) and (2,6) (2, 8) and (2, 6)

                                                                     

The slope a vertical line is _________________________.

The slope of a horizontal line is _____________________.

The ­­­­­­­­­­­­­___________________ is where a function crosses the x-axis.

The ­­­­­­­­­­­­­___________________ is where a function crosses the y-axis.

 

Put each of the following equations into slope-intercept form, y = mx + b.  Identify the slope, m and the y-intercept, b.

y – 2x = 2

y = __________________________  m = ____________________  b = _____________

y = x

 

y = __________________________  m = ____________________  b = _____________

Graph the following equations. Be sure to label the x and y intercepts (if applicable).

y = -2x + 3                                                                    y = -x           

 

 

Caroline has a small business making bath and body beauty baskets.  She estimates that her fixed weekly costs for rent, electricity and salaries is $350.  The products and supplies for one basket cost $5.50.

1. If Caroline makes 20 bath and beauty baskets in a given week, what will her weekly costs be?

2. Caroline’s total costs for last week were $700. How many bath and beauty baskets did she make?
