# What is the equation of the line with slope  m= -2 that passes through  (-1,-8) ?

Jun 19, 2016

$y + 8 = - 2 \left(x + 1\right)$

#### Explanation:

A composition of line should be made at least two point
But the question provide slope and one point
Now we can use slope-form way to solve
GIVEN A POINT$\left(a , b\right)$ AND SLOPE m

The equation of line is $y - b = m \left(x - a\right)$

Use this concept

So the answer is$y + 8 = - 2 \left(x + 1\right)$
