So the book says that I need to determine the slope of the line through the given points. If the slope is undefined, so state.
The problem is (-3,-5) and (-1,-2).
What steps am I suppose to take?
Thank you. I was wondering why 3/2 was positive and -3/2.
I meant to say I wonder why is it 3/2 and not -3/2.
?

slope=rise/run
here (change in rise)/(change in run)
(y2-y1)/(x2-x1)
either point can be 2 or 1
whichever way is easier to subtract
just keep them in the correct order
(-2-(-5))/(-1-(-3))
(-2+5)/(-1+3)
3/2
slope=3/2

Use slope formula. m = (y2 - y1) / (x2 - x1) plug in the points
( -2 - (-5)) / (-1 -(-3))
(3) / (2)
m = 3/2

All you have to do is find the slope so use the equation
m=y2-y1
(over)
x2-x1

change in y / change in x
(-3,-5) and (-1,-2)
[-2-(-5)] /[-1-(-3)]
[-2+5]/[-1+3]
3/2 slope
