line (1,2),(-1,3)

Solution

line

(1, 2), (- 1, 3)

Solution

y = - \frac{1}{2} x + \frac{5}{2}

Solution steps

Find the line

y = mx + b

passing through

(1, 2)

,

(- 1, 3)

Compute the slope

(1, 2), (- 1, 3) : m = - \frac{1}{2}

Compute the

y

intercept:

b = \frac{5}{2}

Construct the line equation

y = mx + b

where

m = - \frac{1}{2}

and

b = \frac{5}{2}

y = - \frac{1}{2} x + \frac{5}{2}
