Question

can somebody check my work please? (I will attach the graph following.)

Find the slope of the line using the two plotted points in the graph.
slope = y2 - y1 / x2 - x1

so

-7 - 5= -2

2- 2= 0

slope = 2/0

Answer 1

It can't be 2/0 for sure because that mean the slope is undefined.

Answer 2

wrong.... the slope it -13/4

Answer 3

how do you get that?

Answer 4

remember that the slope is rise over run. you go -13 for rise and 4 for run

Answer 5

rise/run=change in y over the change in x

Answer 6

(-7-5)/(2-(-2))

Answer 7

Let's choose points (-2, 5) and (2, -7).
\[m=\frac{y_1-y_2}{x_1-x_2}\]
\[m=\frac{5--7}{-2-2}\]
\[m=\frac{12}{-4}\]
\[m=-3\]

Answer 8

@andre33 - It's 12 up, not 13.

Answer 9

-7-5 is 12 sorry not 13

Answer 10

so this is not y2 - y1 and x2 - x1?

Answer 11

honest mistake i working one polar coordinates so my head is backwards...

Answer 12

@adrenaline_rules It doesn't really matter, as long as you stay consistent. If you call the first set of points Point 1, then Y1 would have to be the Y coord of Y1 point.

Answer 13

awesome. Thank you all! I think I got it a little better now.

Answer 14

If you need it.

Answer 15

Thank you!
