Get the equation into slope-intercept form to immediately see your answer to the slope and to the y-intercept.
.
y = m*x + b
m = slope
(0,b) = y-intercept
.
2x + y = 4
y = -2x + 4
m = -2
(0,4) = y-intercept.
.
You only need one more point to be able to draw a line.
A good candidate is to find the x-intercept, which is often asked for.
Set y = 0 and solve for x.
.
0 = -2x + 4
2x = 4
x = 2
(2,0) = x-intercept
.
A graph is always useful.

.
Done.
