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

Solution

line

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

Solution

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

Solution steps

Find the line

y = mx + b

passing through

(1, - 2)

,

(3, - 1)

Compute the slope

(1, - 2), (3, - 1) : 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}
