The equation of a line can be written in the slope-intercept form given to be:


y=mx+b

where m is the slope of the line and b is the intercept on the y-axis.

The equation is given to be:


2x+y=4

To write the equation in the slope-intercept form, we can subtract 2x from both sides:


\begin{gathered} 2x-2x+y=-2x+4 \\ y=-2x+4 \end{gathered}

Therefore, the slope of the line is:


m=-2

and the y-intercept is:


b=4
