Question

What is the slope of the line that passes through the points (-6, 8) and (-9, 7)? Write your answer in simplest form.

Answer 1

Answer:

m=1/3

equation y=1/3x+10

Step-by-step explanation:

Find the rise and run.

1. -6--9=run=3

2. 8-7=rise=1

We are asked to find the slope of the line that passes through (-6, 8) and (-9, 7).

$\triangle~\fbox{\bf{KEY:}}$ (formula for Slope)

$\longmapsto\bf{\cfrac{y2-y1}{x2-x1}}$

y2 & y1 = the y-coordinates of the two points

x2 & x1 = the x-coordinates of the two points

$\ddot\bigstar$ Remember this...

$\fbox{y2\;and\;y1\;are\;y-coordinates\;of\;the\;two\;points,\;and\;x2\;and\;x1\;are\;x-coordinates}}$

So we substitute the values and obtain:

$\bf{\cfrac{7-8}{-9-(-6)}$

Simplifying:

$\bf{\cfrac{-1}{-9+6}}$

Simplifying more:

$\bf{\cfrac{-1}{-3}}$

Divide the top and bottom by -1:

$\bf{\cfrac{1}{3}}$

There's the slope.
