Okay so your slope is going to be -9 because that is the rise over run for that equation. 5 is you y-intercept.

Answer:

The correct option is 2. The slope of the equation is -9.

Step-by-step explanation:

The given equation is

y=-9x+5             ..... (1)

The slope intercept form of a line is

y=mx+b              .... (2)

Where, m is the slope and b is y-intercept.

On comparing (1) and (2), we get

m=-9

and

b=5

Therefore, the slope of the equation is -9 and y-intercept is (0,5). Option 2 is correct.

Suppose that y varies directly with x, and y=15 when x=24. Write a direct variation equation that relates x and y. Find y when x
Lapatulllka [165]

Just set up a proportion with the original numbers and then the numbers you want to find like so: (x1/y1)=(x2/y2) and since you want to find the second y value, just leave y as a variable like so: (15/24)=(3/y) after this just cross multiply and get the answer: 15y=72.....y=4.8

Suppose you want to learn more about the heights of the buildings in New York City. How would you choose a sample of the buildin
natulia [17]

Answer:

I'd use a Non-probability Sampling Method.

Explanation:

The question is already laced with criteria - Heights of Buildings in New York.

This means that there are certain buildings that won't fit in the sample. In a non-probability sample, objects or subjects are elected based on specified criteria that are not random. This means that not all objects/subject have a c<em>hance</em> of being included in the sample.

It is assumed that the question/assignment centers around high rise buildings.

Therefore, one storey buildings and bungalows that are within and outside New York will not be included in the sample.

Under the Non-Probability Sampling Method, it is essential to note that there are other subgroupings of sampling techniques. They are:

  1. Convenience Sample
  2. Voluntary Sample
  3. Purposive Sample
  4. Snowball Sample

Cheers!
