NikAS [45]

Answer:

Step-by-step explanation:

The mean (or average) of a set of numbers can be found with the following formula:

$Mean = \frac{A_{1} + A_{2} + ... + A_{N}}{N}$

For this problem, we have five numbers, so we add them together and divide by 5:

$Mean = \frac{92 + 85 + 78 + 97 + 88}{5}$

$Mean = \frac{440}{5}$

$Mean = 88$

A line has a slope of -1/4 and passes through point (-5/4, 1) What is the equation of the line?

Vedmedyk [2.9K]

The line of the equation would be y = -1/4x + 11/16.

In order to find that, we'll put the ordered pair and the slope into slope intercept form. Then we can solve for the intercept.

y = mx + b
1 = -1/4(-5/4) + b
1 = 5/16 + b
11/16 = b

So then we put that in the equation with slope for the final equation.
