Slope of (0,-3)(3,1) can anytone answer this ? Thanks

The slope of a line is ΔY/ΔX where Δ is the "change" of a value.

ΔY is calculated by subtracting the two Y-coordinates. Keep the order straight. You don't necessarily get a positive number.

an easy way to do this is range over domain (or Y over X)

here is how you name your coordinates,

(X1, Y1)(X2, Y2)

your equation is

m=y2-y1/ x2-x1

Now just fill in your numbers,


1-(-3)
_____ =
3-0

(stay change switch)

1+3
______ =
3+0

4
__
3

your slope is
4/3

I hope this helped you, and if it means anything, I'm 14 (in 8th grade) and we did this in my Algebra class.
