Determine the slope of the line through the given points (-4,1), (-1,-2). State whether the line is the graph of an increasing function, decreasing function, a constant function or not a function.

Question

anonymous · Answer

to find slope you do y2-y1/x2-x1
so -3/-5

anonymous · Answer

How do I tell whether its increasing, decreasing or not at all..I think that part is where i'm actually stuck a bit

anonymous · Answer

correct. to find slope you do y2-y1divided by x2-x1

anonymous · Answer

you will have to look at your paper infront of you. negative is negative and positive it positive.  if the slope is increasing it will be a positive if its decreasing it will usually be descreasing. look on your X and Y axis if they are crossing and stright across then not at all

anonymous · Answer

how is your paper set up?

anonymous · Answer

you will also have to look at the 1, 2, 3 and 4 sides on your graph

anonymous · Answer

if your doing a graph

anonymous · Answer

Wouldn't the formula look like this though >
$$-2-(-1)/-1-(-4) = -1/3$$

anonymous · Answer

This book is horrible. I get more information off the internet to help explain things like YOU Tube than this book.

anonymous · Answer

Oh, wow. I see where I messed that up

anonymous · Answer

i know how you feel, its just like my workbook, and textbook

What grade are you in? And are you taking algebra or pre algebra by chance?

anonymous · Answer

are you getting it by chance?

anonymous · Answer

Sad to say a college algebra class. Been so many years since i've taken Algebra. Horrible after all these years.

anonymous · Answer

and while im on here do you know what the fraction would be of 2.4?

anonymous · Answer

oh its ok lol.

anonymous · Answer

the books suck and dont give any info what so ever.

anonymous · Answer

Yep, getting. I'm assuming this one would be a decreasing function? Not understanding where they determine that.

anonymous · Answer

i cant figure out what the fraction of 2.4 is do u know?

anonymous · Answer

12/5

anonymous · Answer

I'm just not seeing where you get the -3/-5. I keep getting a positive fraction
