A line that includes the point (-9, -2) has a slope of -9. What is its equation in point-slope

9x- y = 79

Step-by-step explanation:

Use the formula    y - y1 = m (x - x1)

point: (-9,-2)  x1= -9   y1= -2

slope: -9

plug everything in    y + 2= -9 (x + 9)

simplify   y + 2= -9x - 81

move the 2 to the other side    y = -9x - 79

move the -9x to the other side    -9x + y = -79

multiply the whole thing by -1 to make the x positive

9x - y = 79

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
