The slope of the line is -2.
Solution:
Given points are (-3, -7) and (2, -17).
Here 
Slope of the line:




m = -2
The slope of the line that passes through the pair of points is -2.
Given:
The formula for total cost is

where, p is the price of item and s is the sales tax rate (as a percent).
You pay $14.77 for an item priced at $14.
To find:
The the tax rate.
Solution:
You pay $14.77 for an item priced at $14. So,
Total cost (T) = $14.77
Price of item (p) = $14
Putting T=14.77 and p=14 in given formula, we get



Multiply both sides by 100.

Divide both sides by 14.


Therefore, the tax rate is 5.5%.
No spaces? like t h i s? or like thiiiss??? is this bugging you ????
anyway
use elimination
multiply secn equation by -1
-3x-2y=-6
add to other equation
-3x-2y=-6
<u>4x+2y=10 +</u>
1x+0y=4
x=4
sub back to solve for y
3x+2y=6
3(4)+2y=6
12+2y=6
minus 12 both sides
2y=-6
divide 2
y=-3
(4,-3)
