  • 28
  • 68
  • -170

Step-by-step explanation:

» Take points (1, -2) and (3, -12) from the table.

☑ General equation of a line is y = mx + c

  • m is the slope
  • c is y-intercept

✍<u> </u><u>F</u><u>o</u><u>r</u><u> </u><u>s</u><u>l</u><u>o</u><u>p</u><u>e</u><u>,</u><u> </u><u>m</u><u> </u>:

{ \tt{slope =  \frac{ - 12 - 2}{3 - 1} }} \\  \\ { \tt{slope =  \frac{ - 14}{2} }} \\  \\ { \tt{m =  - 7}}

✍<u> </u><u>For</u><u> </u><u>y-intercept</u><u>,</u><u> </u><u>c</u><u> </u>:

{ \tt{y = mx + c}}

» Taking point (1, -2):

{ \tt{ - 2 = (1 \times  - 7) + c}} \\ { \tt{c =  - 2 + 7}} \\ { \tt{c = 5}}

{ \boxed{ \tt{y =  - 7x + 5}}}

kolezko [41]

Answer:

$15.75

Step-by-step explanation:

first, figure out the value of the tax. that would be 0.30 because there are 6 cds, and each has a tax of 0.05. next, subtract the tax from the total. that would be 94.50. this gives us the price of the cds alone. lastly, divide the toal by 6. 94.50/6=15.75.
