graph this line using the slope and y-intercept:
y = 1/4x
click to select points on the graph.

I can direct you to the answer (bc my pc won't let me take screenshots)

Step-by-step explanation:

1. Go to Desmos

2. Press "start graphing"

3. It'll take you to an empty graph. In the top left corner enter your equation in.

4. Desmos will graph the line for you

~OR~

Always start at the origin (0,0). When grpahing the lines you always want to do rise over run. In this case it would be

Rise: 1

Run: 4

So move up 1 square and 4 to the right

To find the other part of the line you do the opposite. The rise and run are still the same but negative this time.

Here are some points to help you get started:

(-4,-1)

(0,0)

(4,1)

72 is the answer to this problem

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.
