line (2,1),(8,7)

Solution

line

(2, 1), (8, 7)

Solution

y = x - 1

Solution steps

Find the line

y = mx + b

passing through

(2, 1)

,

(8, 7)

Compute the slope

(2, 1), (8, 7) : m = 1

Compute the

y

intercept:

b = - 1

Construct the line equation

y = mx + b

where

m = 1

and

b = - 1

y = x - 1
