Question 54328
Because this line is in standard form: {{{highlight(Ax+By=C)}}}, it's easiest to graph it by finding the x and y intercepts, plotting them, and connecting the dots.
x-2y=4
Let x=0 and solve fot y in order to find the y intercept.
0-2y=4
-2y=4
-2y/-2=4/-2
y=-2
Plot (0,-2)
Let y=0 and solve for x to find the x intercept.
x-2(0)=4
x-0=4
x=4
Plot (4,0)
Connect the dots and you should have a line that looks like:
{{{graph(300,200,-10,10,-10,10,(1/2)x-2)}}}
Happy Calculating!!!
