What is the slope of the line that goes through the points (-4,1) and (4,-5)?

-4/3

Step-by-step explanation:

1. The slope formula is in the form y2-y1/x2-x1

2. Use one set of points as (x1, y1), and the other as (x2, y2).

3. Plug the points into the corresponding equation variables

4. Solve: (-4 - 4)/(1 -(-5)) = -8/6

-8/2 = -4, 6/2 = 3

-8/6 = -4/3

-3/4

Step-by-step explanation:

Use the slope formula to find the slope of the line. Let (-4,1) be (x1,y1) and (4,-5) be (x2,y2).

So, the slope of the line that goes through the points (-4,1) and (4,-5) is .

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
