$y = - 2 x + 1$

Explanation:

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

•color(white)(x)y=mx+b

$\text{where m is the slope and b the y-intercept}$

$\text{here "m=-2" and } b = 1 \to \left(0 , \textcolor{red}{1}\right)$

$\Rightarrow y = - 2 x + 1 \leftarrow \textcolor{red}{\text{is the equation}}$
