Question

Using the given points, determine Δy.

(-3, -5) and (0, 10)



Δy = 3

Δy = 5

Δy = 13

Δy = 15

Medal for the best answer, please explain how you got it! Thank you!!! :)

Answer 1

Hey Natalie c:

Our slope equation gives us:\[\Large\rm m=\frac{\Delta y}{\Delta x}\]The change in y divided by the change in x.
So in this question, they're only concerned with the `difference` in the y values.

Answer 2

So how far apart are the y values in the given set of points?

Answer 3

Hi, Zepderix c:
I am confused, a little. What do I need to divide? I have different equations, but I am still confused on which one to use and what numbers from the ordered pair to use.

Answer 4

No division :o
When we're looking for `slope`, we're doing some division.
I was just providing that equation as a reference.

But here, we need only find out how `far apart` our y values are.
We have a y value located at 10,
and another located at -5,
yes?

So how far apart are those numbers? :)
