Which is an equation in point slope form from the line that passes through the points (4, 5) and( -3, -1 )

6/7

Step-by-step explanation:

Equation of the line:

y = 0.85714285714286x + 1.5714285714286

or

y =  

6x

7

+  11

7

When x=0, y = 1.5714285714286

When y=0, x = -1.8333333333333

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.
