Answer:
A) -2/5
Step-by-step explanation:
Note that for a slope, the slope of the line is found by using the equation:
slope = (rise/run).
In this case, find two points. For example, i will use:
(0, 2) & (5, 0). (x = 0, y = 2) ; (x = 5, y = 0)
Note that "rise" = y, and "run" = x. Plug in the corresponding numbers for the corresponding points.
(2 - 0)/(0 - 5) = slope
Simplify
(2)/(-5) = slope
-(2/5) is your answer.
Note that it does not matter where the negative sign is placed.

Answer:
32%
Step-by-step explanation:
Given
Cost of Crockpot = $125
Coupon = $40
Coupon applies on items greater than $100
Required
Percent saved if coupon is applied.
If she applies coupon on the Crockpot, then she'll be saving $40.
Percent Savings = Amount Saved / Total Amount
Percent Savings = $40/$125
Percent Savings = 0.32
Convert to Percentage
Percent Savings = 0.32 * 100%
Percent Savings = 32%.
Hence, she'd save 32% if she applies the coupon of $40 on the Crockpot
Ok, so 120 pages plus the 60% of the book she has left to read will give the total number of pages.
That means that 120 pages is 40% of the book.
Make a proportion
120/40% = x/60%
72 = .4 x
x = 180 pages
2x + y = 0
2x + 3 = 0
- 3 - 3
2x = -3
2 2
x = -1¹/₂
(x, y) = (-1¹/₂, 3)
