Question 180685
Yes it is!
To see this, put the equation into the "slope-intercept" form: y = mx+b where m = slope and b = y-intercept.
{{{2x+y = 4}}} subtract 2x from both sides of the equation.
{{{y = -2x+4}}} compare this with:
{{{y = mx+b}}}
{{{m = -2}}} and {{{b = 4}}}
The slope is -2 and the y-intercept is 4.
