How do you write an equation in point slope form given (–1, 5) with a slope of 2?

Feb 26, 2016

$2 x - y + 7 = 0$

Explanation:

$\left(- 1 , 5\right) \equiv \left({x}_{1} , {y}_{1}\right)$
Slope = m= 2

By slope point form,

$y - {y}_{1} = m \left(x - {x}_{1}\right)$

$y - 5 = 2 \left(x + 1\right)$

$y - 5 = 2 x + 2$

$2 x - y + 2 + 5 = 0$

$2 x - y + 7 = 0$
