It is C because when you calculate you can see I it has more change

So the rate of change can be found in different places.

For the first one:

This equation is in slope-intercept form, or y = mx + b.

m would be the slope/rate of change, and b the y intercept. (x and y would just be any sets of ordered pairs that fit into the equation.)

So if you look at which number is in the m spot, or the rate of change spot, you see that 5 is the rate of change.

For the second one: The formula for slope is:

m = \frac{ y_{2} -  y_{1} }{x_{2} -  x_{1} }

So just put in any ordered pairs in. I'm just going to put in the ordered pairs, (6, 30) and (4, 22).

Or,

m = (30 - 22) / (6 - 4)

Or,

m = 8/2

Or 4.

For the third one:

You can use the same formula as I stated above.

So you have to look for two ordered pairs here, two points.

So you can estimate that two of the points are: (0, 3) and (-2, -9).

So then just solve for that.

(-9 - 3) / (-2 - 0) = -12 / -2 = 6

For the last one:

Again, use the same equation.

m = (7 - 1) / (-1 - (-3))

 m = 6/2 

m = 3

So the one with the greatest rate of change would be C.

If the area of the triangular kite is 24 square ft and its base is 4 feet, find the height of the kite.
beks73 [17]
Area of a triangle is   A = (1/2) (b) (h).  Here we are given A and b and need to find h.

A = 24 ft^2 = (1/2) (4 ft) (height)

24 = 2(height)          =>          height is 12 ft            (answer)

Can you answer the questions below
DerKrebs [107]
I think the easiest way to answer all of these is to just go ahead and find the equation of the line first. 

I'm pretty sure that by the time you reach this problem, you've learned to find
the equation of a line that passes through two given points.  You have two points:  (2, 100) and (5, 205).  The equation of the line through them is [ y = 35x + 30 ].

6).  The initial membership fee ... the cost for walking in the door and signing up,
before any months, is $30.  (Also the y-intercept.)

7).  The cost per month is $35.  (The slope of the line.)

8).  We already did that, up above.  [  y = 35x + 30 ].

9).  'x' in the equation is the number of months.
There are 12 months in one year.

y = 35(12) + 30 = $450

Use elimination to find the solution to the system of equations.
Stolb23 [73]
Multiply the first equation by 2 to give

10x + 2y = 20

2x - 2y = 4   Adding to elininate y

12 x = 24
x = 2

Plug x = 2 into 2x - 2y = 4

4 - 2y = 4
y = 0

so the answer is 

(2,0)
