What is the slope and y-intercept of the line 2x-y=1?

Mar 15, 2018

$\text{slope "=2" y-intercept } = - 1$

Explanation:

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

•color(white)(x)y=mx+b

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

$\text{Rearrange "2x-y=1" into this form}$

$\Rightarrow y = 2 x - 1 \leftarrow \textcolor{b l u e}{\text{in slope-intercept form}}$

$\text{slope m "=2" and y-intercept } = - 1$
