line (3,18),(15,3)

Solution

line

(3, 18), (15, 3)

Solution

y = - \frac{5}{4} x + \frac{87}{4}

Solution steps

Find the line

y = mx + b

passing through

(3, 18)

,

(15, 3)

Compute the slope

(3, 18), (15, 3) : m = - \frac{5}{4}

Compute the

y

intercept:

b = \frac{87}{4}

Construct the line equation

y = mx + b

where

m = - \frac{5}{4}

and

b = \frac{87}{4}

y = - \frac{5}{4} x + \frac{87}{4}
