Question

PLEASE HELP IF YOU CAN!


I did the equation the right way. At least, I think I did the equation the right way. When I look at the textbook, it says I did the equation the right way. But my teacher says I got it wrong.

I had to find the slope of a line. Point A(-1, 4), Point B(3, 1), and Point C(0,-3). The slopes I had to find were Line AB, Line AC, and Line BC.

For AB=3/4
AC=-1
BC=-4

If you could please help me and tell me where I went wrong and how to do it correctly, it would mean the world to me! PLEASE

Answer 1

How did you get 3/4 for slope of AB?

Answer 2

4-1/3-(-1)

Answer 3

If you use [3 - (-1)] in the denominator, then the numerator must be [11 - 4]

Answer 4

Your slope for AC is correct, but BC can't have a negative slope: it is going up and to the right.

Answer 5

Hmm, okay...

So, how do I fix AB and BC?

Answer 6

Look at the picture I drew (or better yet, draw your own on some paper in front of you) and look at the 'rise-over-run.'

Answer 7

Hang on....You said that the numerator for AB would have to be (11-4)...where'd you get the 11?
