Please Help The humane society has puppies up for adoption the weight in pounds of the puppies currently at the Humane Society or 17, 14, 13, 15, 21, 39, 18, 22, and 14
Using a stem and leaf plot
(A) what weight interval has the most puppies? What fraction of the total does the interval represent?

y = 3x+4

step-by-step explanation:

to find the slope

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

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.

step-by-step explanation:

tangent z: 4/3

cosine y: 4/5

cotangent y: 4/3
