What is the slope of the line through (6, 9) and (7, 1)<br>a. -1/8<br>b. 8<br>c. -8<br>d. 1/8​
eduard

Answer:

Slope is  -8

Step-by-step explanation:

First and foremost, welcome to Brainly!

I'll begin with the basics of slope, just to help you get the gist of this crucial concept -

Slope can be rewritten as rise/run, although written formally as :

m = \frac{y_{2}-y_{1}  }{x_2-x_1}

when we are given two coordinates (x,y) on the line.

One important thing to note is that slope belongs to a general equation,

y = mx+b

where b represents the y intercept and m is slope.

We're given two coordinates in your question: (6,9) and (7,1):

m = \frac{1-9}{7-6} = \frac{-8}{1} =-8

m = -8 is the final answer.

I hope this helps! By the way, slope is a concept that will follow you to calculus and physics, so I urge you to practice!
