Question

Find the equation of a line with the given points.

(Put your answers in the form y=mx + b.)

(8,1)
(7,9)​

Answer 1

The slope between the two given points is -8.

Explanation:

1. Know the formula for finding the slope between two points.

`Slope(m)=(y2-y1)/(x2-x1)`

2. Use (8,1) as your (x1,y1) and use (7,9) as your (x2,y2).

`m=(9-1)/(7-8)`

3. Simplify the equation so you can find your slope.

`m=(8)/(-1) = -8`

So, the slope between (8,1) and (7,9) is -8
