You can put this solution on YOUR website!
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%28y=mx%2Bb%29, where m=slope and (0,b)=y-intercept
You should have gotten:
y=%28-1%2F2%29x%2B2 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%28300%2C200%2C-10%2C10%2C-10%2C10%2C%28-1%2F2%29x%2B2%29
Happy Calculating!!!
