Question

What is the slope of the line shown below? (9, 1) (-3, -7)

Answer 1

2/3

Explanation:

I like the line up and subtract strategy. At the end you just put 2nd number over 1st.

This is the slope formula; just a different way to think about the formula.

(9,1)

-(-3,-7)

=======

12, 8

So the slope is 8/12=2/3.

Answer 2

2/3

Explanation:

To find the slope based off of two points, use the following formula:

`(y2-y1)/(x2-x1)`

Plug in your values and simplify.

`(-7-1)/(-3-9) \\\\(-8)/(-12)`

`(8)/(12)`

`(2)/(3)`
