What is the slope of the line that passes through the points (-2,7) and (2,-5) in simplest form ?

The answer is -3.

Step-by-step explanation:

You have to figure out the formula. X1 is -2. X2 is 2. Y1 is 7. Y2 is -5. After that, you must subtract Y2-Y1 and X2-X1. -5-7 is -12. 2--2 is 4. After that, you must simplify. You got -12/4. When you simplify, you get -3.

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25

pls mark as brainliest

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3
