Find the slope of (1, 2), (-1, -2). reduce all fractional answers to lowest terms

The slope is 2

Step-by-step explanation:

The slope is equal to

m = (y2-y1)/(x2-x1)

   = (-2-2)/(-1-1)

   = -4/-2

   = 2

5.5

step-by-step explanation:

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%

you.
