Question

1. What is the slope of the line that passes through points (-8,3) and (1,9)?

Answer 1

2/3 (the first one)

Explanation:

let's use

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

plug in the numbers

`(9-3)/(1-(-8))`

which becomes

`(9-3)/(1+8)`

then simplify to

`(6)/(9)`

then can be simplified again to

`(2)/(3)`

if you divide 6/9 by 3

so

m = 2/3

which is the first one

Answer 2

The slope should be 8 1/3 which is also 25/3
