What is the equation in point-slope form of the line given m=-2;(0,1)?

$y - 1 = - 2 x$

Explanation:

$\text{the equation of a line in "color(blue)"point-slope form}$ is.

•color(white)(x)y-y_1=m(x-x_1)

$\text{where m is the slope and " (x_1y_1)" a point on the line}$

$\text{here "m=-2" and } \left({x}_{1} , {y}_{1}\right) = \left(0 , 1\right)$

$\Rightarrow y - 1 = - 2 \left(x - 0\right)$

$\Rightarrow y - 1 = - 2 x$
