Question

Really need help!
If a line goes through points (-2, 9) and (0, 3), what is its slope?
-3
3
6
-1/3

Answer 1

Slope = difference in y divided by difference in x.
Subtract the y-coordinates.
In the same order, subtract the x-coordinates.
Divide the first result by the second result.
That is the slope.

Answer 2

So 9-3=6
-2-0=-2
So 6 divided by 2?
=3? or -3?

Answer 3

Answer 4

You are correct in the operations you did.
6/(-2) = -3
The slope is -3.
When you divide positive by negative, you get negative.
