What equation is graphed in this figure? y+2=−32(x−2) y−3=32(x+1) y+1=−23(x−3) y−4=−23(x+2) Number graph that ranges from negati

Answer:

$y+2=-\frac{3}{2}(x-2)$

Step-by-step explanation:

Given:

Two points on a line are given as:

(0, 1) and (2, -2)

We know that the slope of a line passing through points $(x_1,y_1)\ and\ (x_2,y_2)$ is given as:

$m=\frac{y_2-y_1}{x_2-x_1}$

Plug in $x_1=0,y_1=1,x_2=2,y_2=-2$ . This gives,

$m=\frac{-2-1}{2-0}\\\\m=\frac{-3}{2}=-\frac{3}{2}$

The equation of a line with slope 'm' and points $(x_1,y_1)\ and\ (x_2,y_2)$ is given as:

$y-y_1=m(x-x_1)\\\\or\\\\y-y_2=m(x-x_2)$

Now, on plugging in the second point $(x_2,y_2)=(2,-2)$ we get:

$y-(-2)=-\frac{3}{2}(x-2)\\\\y+2=-\frac{3}{2}(x-2)$

Therefore, the first option is correct which is given as:

$y+2=-\frac{3}{2}(x-2)$

I hope this helps you

Based on probability and if it is appropriate for a decision to be left up to chance, choose every situation that is both statis

svet-max [94.6K]

The situations that are both statistically fair and morally fair are Situation 2, Situation 3 and Situation 5

<h3>How to categorize the situations?</h3>

For a situation to be fair, the probability of every outcome must be equal.

We can now analyze each option using the above highlight

Situation 1

Alphabets = 26
Probability of vowel = 5/26
Probability of consonant = 21/26

The probabilities of vowels and consonant are not equal.

Hence, this situation is not fair

Situation 2

People = 4

P(Each) = 1/4

The probability of each participant is equal in the above scenario i.e. 1/4

Hence, this situation is fair

Situation 3

People = 5
P(Each) = 1/5

The probability of each cousin is equal in the above scenario i.e. 1/5

Hence, this situation is fair

Situation 4

Numbers = 5 i.e. 2 to 6
P(Prime) = 3/5
P(Composite) = 4/6

The probabilities of prime and composite numbers are not equal.

Hence, this situation is not fair

Situation 5

Roommates = 5
Cards = 5
Aces = 4
P(Each) = 1/5

All probabilities are equal in the above scenario i.e. 1/5

Hence, this situation is fair
