Slope is -3 or #m = -3#

Explanation:

For finding slope, you need to follow this simple formula which is:

#(y_1-y_2)/(x_1-x_2)# or if you understand this, #(Deltay)/(Deltax)# which means change in y over change in x, you can do that too.

The y represents the y values (the second number) in the ordered pairs and the x represents the x values (the first number). By inputting the numbers into the formula, it should look like this:

#(0-(-3))/(2-3)# = #(0+3)/(2-3)#= #3/-1# = #-3#

There's no specific #y_1# or #y_2#, you just name one of the y values #y_1# and the other y value #y_2#. Same thing for x. For example, this is what happens if I switch it:

#(-3-0)/(3-2)# = #(-3)/(3-2)#= #-3/1# = #-3#

You get the same answer!
I hope this helps!

Here's a song thing that might help:
Change in y over change in x,
Rise over run but what happens next?,
divide the two, and then reduce
then you got slope, slope, slope, slope, slope, slope, slope.

(Its a parody of the song "Low")
