  1. A pre-test does not count against your grade. It's like a pass or fail type of thing. Do your best! I know you can get through it! :) ♥

  3. #1,4,5,12,14. no graph
    #2. remember the slope-intercept form? It's called that for a reason
    #3. usually it's y=mx+b, so not B
    not C because there is no x
    not -5x because that means the cost goes down for more hours.
    #6,7,12,13. see #2
    #8. slope is defined as y-change divided by x-change, so (8-0)/(3-1)
    #9,10. The x/y-intercept is where the graph crosses the x/y-axis
    #11. see #8
