Question 57645
Find the slope of the line and sketch the graph. 
x+2y=4 
If you know how to find the slope, you can also find the y-intercept from the slope intercept form of a line:{{{highlight(y=mx+b)}}}, where m=slope and (0,b)=y-intercept
You should have gotten:
{{{y=(-1/2)x+2}}}  When you found your slope.
You're right the slope is: m=-1/2
The y-intercept is (0,2)
Plot (0,2) it's 0n the y-axis at 2
Now use your slope to plot a second point.  Slope=rise/run.  Your rise is -1, so go down 1, and your run is 2, so go right 2. Plot your second point (you should be at (2,1)).
Connect your points and you have a line that should look like this:
{{{graph(300,200,-10,10,-10,10,(-1/2)x+2)}}}
Happy Calculating!!!
