2. would have a slope of -1.66

3.would have a slope of 0

4. would have a slope of -13

Step-by-step explanation:

(Y2 - Y1) / (X2 -X1)

1. (9-5) / (4-2) = 4 / 2 =2

2. (-5-5) / (3 - -3) = -10 / 6 = 1.66

3. (2 - 2) / (5 - -4) = 0 / 9 = 0

4. (-7 - 6) / (3 - 3) = -13 / 0 = -13

Santa gave kittens to 13 boys and girls. What is the ratio of kitten ears to kitten tails?
SVEN [57.7K]

Answer:

Ratio = 2 : 1

Step-by-step explanation:

Given

Population = 13 --- Boys & Girls

Required

Determine the ratio of the kitten ears to the tails

A kitten has 1 tail and 2 ears.

Assume each individual got 1 kitten each

This implies that,

Number\ of\ tails= 1 * 13

Number\ of\ tails= 13

Number\ of\ ears= 2* 13

Number\ of\ ears= 26

The ratio of ears to tail is then calculated as follows:

Ratio = Number of ears : Number of tails

This gives

Ratio = 26 : 13

Divide by 13

Ratio = 26/13 : 13/13

Ratio = 2 : 1
