Answer:
The function is
.
The slope is
.
The y-intercept is
.
Step-by-step explanation:
Our aim is to calculate the values <em>m</em> (slope) and <em>b</em> (y-intercept) in the equation of a line :

We have the following data:

To find the line of best fit for the points given, you must:
Step 1: Find
and
as it was done in the table below.
Step 2: Find the sum of every column:

Step 3: Use the following equations to find <em>b</em> and <em>m</em>:

Step 4: Assemble the equation of a line

The graph of the regression line is:
Answer:
y +8 = -4(x -8)
Step-by-step explanation:
You recognize that the given equation is in slope-intercept form:
y = mx + b
with m = 1/4 and b = 5.
A perpendicular line will have a slope that is the negative reciprocal of this value of m, so the desired slope is ...
-1/m = -1/(1/4) = -4
The point-slope form of the equation for a line is ...
y -k = m(x -h) . . . . . for slope m through point (h, k)
Using m=-4 and (h, k) = (8, -8), the point-slope form of the equation for the line you want is ...
y +8 = -4(x -8)
