Answer:
C.
Step-by-step explanation:
Choose two points on the line and find the slope. For example, let's use coordinates (0,2) and (5,4).
Use the slope formula to find the slope between these points.
y2-y1/x2-x1
4-2/5-0 = 2/5
Slope of the new line is 2/5.
With the slope, compare the two fractions. Set them up side by side and cross multiply. Whichever one gives you the larger number is the larger fraction. Larger slopes are going to be steeper. So, C is right.
Refer to my picture to see what I mean by cross multiplying.

Let x be the original price.
Discount percentage = 40%
Price after discount = $3
So, x - = 3
= 3
= 3
x = 5
Hence, the equation that would allow us to find the original price is 0.6x = 3.
Answer:
The number is 12
Step-by-step explanation:
[] First, let's turn all these words into something mathematical. N will equal "my number"
-><u> If you add 12 to my number</u> and then multiply the result by 3, you will get 64 more than two-thirds of my number.
-> n + 12 <u>and then multiply the result by 3</u>, you will get 64 more than two-thirds of my number.
-> 3(n + 12), you will get 64 more than <u>two-thirds of my number</u>.
-> 3(n + 12) = <u>64 more than</u>
-> 3(n + 12) = 64 +
[] Phew, okay. Now it is something we can solve and less scary;
[Given]
3(n + 12) = 64 +
[Distribute]
3n + 36 = 64 +
[Multiply both sides by 3]
9n + 108 = 192 + 2n
[Subtract 108 and 2n from both sides]
7n = 84
[Divide both sides by 4]
n = 12
