Answer:

y = 3/7 x - 12/7

Step-by-step explanation:

The slope is (0+3)/(4+3) = 3/7

So, now you have a point and a slope, so use the point-slope form. That gives you

y-0 = 3/7 (x-4)

Now just rearrange to slope-intercept form.

y = 3/7 x - 12/7

You have to use the y2-y1 over x2-x1.
So, let's plug the numbers in.
(-3,-3)
^ ^
X1 Y1
(4,0)
^ ^
X2 Y2
So, that would be
0-(-3)
——
4-(-3)
The two subtraction signs counteract and become a positive, or addition symbol. So it would be
0+3
——
4+ 3
Do the addition to get 3 over 7 or
3
—
7

Answer:a) mean=167.1

b)median=168.5

c)mode= 180

Step-by-step explanation:

Mean= total sum of values in the data set/ number of values

=2339/14=167.1

Median = midpoint = 165+172/2= 337/2= 168.5

Mode= number with the highest number of frequency, for this data set, 180 occurred most because it occurred three times
