Answer:

Step-by-step explanation:

Actually, the answer is the second graph from the left. In

y=3sin\frac{1}{3}x , the 1/3 represents the "b" value in the equation for the period (length of one revolution) of the function. The period is found in

\frac{2\pi}{b} and since our b value is 1/3:

\frac{2\pi}{\frac{1}{3} }=\frac{2\pi}{1}*\frac{3}{1}=6\pi

That means that one revolution is 6pi units long. The amplitude (the number out in front of the sin) is how high it goes up and down from the midline (the x-axis). The third graph from the left shows a function with a period of 2pi, which is the normal period for a sin function.

<h3>Answer:   -4</h3>

==========================================================

Explanation:

We can pick any two rows from the table to get the (x,y) points needed to find the slope.

Let's say we pick the second and third rows

Subtract the y values: 14-6 = 8

Subtract the x values in the same order: 1-3 = -2

Divide the differences: 8/(-2) = -4

The slope is -4

--------------------------------------------------

You can use the slope formula

Let's say the points are (x1,y1) = (1,14) and (3,6)

m = (y2-y1)/(x2-x1)

m = (6-14)/(3-1)

m = -8/2

m = -4

It's the same basic idea as the previous section. You subtract the y values together (y2-y1) and the x values together (x2-x1) and divide the differences to get m. The order of subtraction doesn't matter as long as you stay consistent. If you do something like y2-y1 and x1-x2, then you'll get the wrong slope value.
