Answer:
See below ~
Step-by-step explanation:
<h3>What number represents the slope?</h3>
The slope refers to the rate of change of the equation.
Here, the slope is 1473 as that is the value that is multiplied on increasing the number of classes.
It represents the price per class.
<h3>What number represents the y-intercept?</h3>
The y-intercept refers to where the line intersects the y-axis.
Here, the y-intercept is 5495.
It represents the one time fee for room and board.
Y = -3x + 6 = 9
-3x = 3
x = -1
solution is (-1, 9)
6.40 units
You use the squaring method to fill in the triangle.
Count the sides 4 up and 5 across
Square them (16 and 25)
Add them together 16+25=41
Find the square root of 41 (6.40)
Good luck!

Answer:
Step-by-step explanation:
given a point
the equation of a line with slope m that passes through the given point is
or equivalently
.
Recall that a line of the form
, the y intercept is b and the x intercept is
.
So, in our case, the y intercept is
and the x intercept is
.
In our case, we know that the line is tangent to the graph of 1/x. So consider a point over the graph
. Which means that 
The slope of the tangent line is given by the derivative of the function evaluated at
. Using the properties of derivatives, we get
. So evaluated at
we get 
Replacing the values in our previous findings we get that the y intercept is

The x intercept is

The triangle in consideration has height
and base
. So the area is

So regardless of the point we take on the graph, the area of the triangle is always 2.
