how to solve attached

Answer 1

do you know slope formula firsit?

Answer 2

1. find slope using lope formula: (y1-y2)/(x1-x2)

Answer 3

2. write this y=mx+b where

Answer 4

m is slope

Answer 5

substitute one of the point into equation where you know sloep and coordinates

Answer 6

3.5-8.5/1--3

Answer 7

4/5 then

Answer 8

no

Answer 9

so sloe is -5/4

Answer 10

now substitue one of the points into equation y=-5/4x+b find b

Answer 11

1=3.5*-5/4+b

Answer 12

b is y intersept

Answer 13

i should then write as 3.5x-5/4?
