What is the slope of line segment AB? Keep as a reduced fraction.<br> B<br> A

ladessa [460]

Answer:

Step-by-step explanation:

Use rise over run (y2 - y1) / (x2 - x1) where (x1, x2) and (y1, y2) are points on the line

Plug in the points A (-3, -2) and B (1, 6)

(y2 - y1) / (x2 - x1)

(6 + 2) / (1 + 3)

8 / 4

= 2

So, the slope of line segment AB is 2.

Pia bought a pair of shoes on sale for 30% off. If pia paid $63 for the pair of shoes, what was the original price?

cluponka [151]

So if she got them at 30% off that means

$63 = 70%
divide both sides by 70 to get 1%
$0.90 = 1%
multiply by 100 to get full price
$90 = 100%

original price was $90

Do these ratios form a proportion?

telo118 [61]

Answer:

No, because both of them will never be able to match; become equivalent. You would have to multiply 2 different numbers to make them match, meaning they would not be proportional. For a comparison to be proportional, the ratio you are trying to simplify to must be achieved by multiplying 2 numbers from the previous ratio by one LCD.

$\frac{3\cdot 4}{7 \cdot 3} = \frac{12}{21}$

They are<em> able</em> to make 12/21, but that does not mean they are proportional.
