Hi there!

To find the slope of a line when we have 2 points, we use this formula:

m=\frac{y2-y1}{x2-x1}

where m is the slope.

\frac{7-7}{7-3}

Notice that if we subtract the y-coordinates, we get 0. We know that 0 divided by any number is 0.

So the slope of this line is 0.

So if the y-coordinates are the same, then the slope is 0.

Now, let's find the slope of the next line.

\frac{-5-3}{-4-(-4)} \\\frac{-8}{-4+4} \\\frac{8}{0}

Do you see what I see?

We cannot divide by 0 because division by 0 is undefined. So the slope of this line is undefined.

Remember:

  • If the y-coordinates are the same, then the slope is 0.
  • If the x-coordinates are the same, then the slope is undefined.

Hope this helps you!

The number of cases of a new disease can be modeled by the quadratic regression equation y = –2x2 + 36x + 6, where x represents
nirvana33 [79]

Since x represents the year, year 15 will be 15 years.

Plug in "15" as your "x"

y = -2(15)^2 + 36(15) + 6

15^2 = 225 (Exponents come before multiplication)

y = -2(225) + 36(15) + 6

y = -450 + 540 + 6

y = 90 + 6

y = 96

<em>The answer is B</em>
