1. [tex]y = - 0.5x + 5.5[/tex]

   Step-by-step explanation:

   finding the slope

   [tex]\frac{3 - 1}{5 - 15} = - \frac{1}{2}[/tex]

   m is the slope

   [tex]- 0.5x + b = y[/tex]

   we can get y from any point but that goes for x,too

   [tex]- 0.5(5) + b = 3 \\ b = 2.5 + 3 \\ b = 5.5[/tex]

   the equation is

   [tex]y = -0.5x + 5.5[/tex]

2. y = 11/5x - 32/5

   Step-by-step explanation:

   y2 - y1 / x2 - x1

   -2 - 9 / 2 - 7

   -11 / -5

   = 11/5

   y = 11/5x + b

   -2 = 11/5(2) + b

   -2 = 22/5 + b

   -32/5 = b

3. $450.00 for 6 weeks

   or

   $300

   step-by-step explanation:

   $200.00 for first week $50.00 x5 equals $250 plus $200 equals $450.00 for six weeks.

   $200 for first week

   $200 x 0.10 = $20

   $20 x 5 = $100

   $200 + $100 = $300

4. y = 4x - 7

   Step-by-step explanation:

   Finding the slope:

   [tex]\frac{13+15}{5+2}=\frac{28}{7}=\boxed{4}[/tex]

   The slope is 4.

   Finding the y-intercept:

   [tex]y=4x+b\\\\13=4(5)+b\\\\13=20+b\\\\13-20=20-20+b\\\\\boxed{-7=b}[/tex]

   The equation is [tex]y=4x-7[/tex].

   Hope this helps.
