Answer:

Mean Age: 13 years

Step-by-step explanation:

To find the mean or average in mathematics, add up all data in a set, and divide by the amount of individual values there are in the set.

Here's what I mean:

12+14+12+15+14+13+12+12 = 104 / 8 different ages in the set = 13

A line goes through the point (-8,9), and has a slope of 3/4

olya-2409 [2.1K]

Answer:

$y=\dfrac{3}{4}x+15$

Step-by-step explanation:

Given that,

A line goes through the point (-8,9), and has a slope of 3/4.

We need to express in the form of Ax+B for this line.

We have, m = 3/4

So,

$y=\dfrac{3}{4}x+B$

Put y = 9 and x = -8 in the above equation.

$9=\dfrac{3}{4}(-8)+B\\\\9=-6+B\\\\9+6=B\\\\B=15$

So,

$y=\dfrac{3}{4}x+15$

It is the required equation of the line.
