Write an equation of the line that passes through a pair of points:

vredina [299]

Answer:

The equation of the line that passes through a pair of points

$y = \frac{-1}{8} ( x ) -\frac{11}{8}$

Step-by-step explanation:

Explanation:-

Given points are ( 5 ,-2) and ( 3,-1)

slope of the line

$m = \frac{y_{2} -y_{1} }{x_{2}-x_{1} } = \frac{-1-(-2)}{-3-(5)} = \frac{1}{-8}$

The equation of the line that passes through a pair of points

$y - y_{1} = m ( x - x_{1} )$

$y - (-2) = \frac{-1}{8} ( x - (5) )$

$y = \frac{-1}{8} ( x ) +\frac{5}{8} -2$

$y = \frac{-1}{8} ( x ) +\frac{5-16}{8}$

$y = \frac{-1}{8} ( x ) -\frac{11}{8}$
