You have the y-intercept of -4. That means that the line will go through the point (0, -4). Choices B and C do that. Plug in 1 for x and find y.

y = 2x - 4

y = 2 * 1 - 4

y = 2 - 4

y = -2

In graph B, when x = 1, y = -3.5,  which is incorrect.

In graph C, when x = 1, y = -2

Graph C is the correct answer.

Anyone??? need some help huys:)
atroni [7]

Slope-intercept form:

y = mx + b        "m" is the slope


First i would isolate the "y" in the equation.

2x + y = 4       Subtract 2x on both sides

2x - 2x + y = 4 - 2x

y = 4 - 2x    or     y = -2x + 4

The given line's slope is -2.


For lines to be perpendicular, their slopes have to be the opposite/negative reciprocals (flipped sign and number)

For example:

slope is 2

perpendicular line's slope is -1/2

slope is -2/3

perpendicular line's slope is 3/2


The given line's slope is -2, so the perpendicular line's slope is 1/2.

The 3rd option is your answer

Micah pays 54$ for an item originally priced 60$. What percentage of the original price was his discount?
pantera1 [17]

Answer: The percentage of the original price was his discount = 10%

Step-by-step explanation:

Given: original price = $60

Price after discount =  $54

Discount = Price after discount  - original price

= $ (60-54) = $6

The percentage of the original price was his discount = \dfrac{Discount}{Original\ price}\times100

=\dfrac{6}{60}\times100\%\\\\=\dfrac{1}{10}\times100\%\\\\=10\%

Hence, the percentage of the original price was his discount = 10%
