Problems You Should Try

    Directions:  Please calculate the equation of the line with the given slope that intersects the given point.

1. m=2, (2,4) 2. m=-3, (-2,3)
3. m=1/2, (1,5) 4. m=2/3, (4,-4)
5. m=4/5, (10,-8.6) 6. m=0, (5,4)
7. m=1.8, (1/2,4/3) 8. m=100, (203,506)

     Directions:  Please calculate the equation of the line that intersects the given points.

1. (-5,-1/3) & (0,3) 2. (0,0) & (-2,3)
3. (-3,-12) & (-1,-4) 4. (-1,4) & (2,1)
5. (-4,2) & (2,2) 6. (0,3.5) & (7,11.5)
7. (5,2) & (7,1.6) 8. (2,-2) & (-3,3)

    Directions:  Please answer the following word problems.

1.  A lawyer gets paid a retainer and an hourly fee.  The hourly rate for the lawyer is $500 per hour.  The lawyer collects $1750 for 3 hours work.  Write a linear equation that reflects the lawyer's pay scheme.

2.  A company sells potato chips.  When they sells 10 boxes of chips, their profit is $24.  When they sell 18 boxes of potato chips, their profit is $38.  Write a linear equation that reflects the profit scheme for this company?  What is their profit on selling 102 boxes of chips?
