Answer 1

y1-y2/x1-x2

Answer 2

You choose any two points.

For example
(3, 86) and (7, 61)

And then plug and chuck in to the formla
\(\sf\Large Slope = \frac{\color{blue}{y_2}-\color{red}{y_1}}{\color{green}{x_2}-\color{purple}{x_1}}\)

Where the two points are in the form:

\(\sf\Large (\color{purple}{x_1},\color{red}{y_1})~and~(\color{green}{x_2},\color{blue}{y_2})\)

Answer 3

Yes, I get -6.25x

Answer 4

And the answer is -4.6x

Answer 5

Full answer is y=-4.6x+96... I got it right the first time but I went back and checked it and I have no clue what happened

Answer 6

You're not supposed to get any 'x' in the slope

If you look at what I posted, I even tried to make it colorful so you can easily plug and chug

Answer 7

Yeah.
86-61
3-7

Answer 8

25/-4

Answer 9

Slope is -6.25

Answer 10

And that is the correct slope, your book has an incorrect slope

maybe they meant to write -6 1/4 and not -6.4

Answer 11

Hmm... I'll ask my teacher then. Thanks. I guess I wasn't imagining things

Answer 12

No problem! ^-^
