To plot this graph, we just need two points. So let's find the x and y intercepts.

x-intercept


To find the x-intercept, plug in y=0 and solve for x


x-2y=4 Start with the given equation.


x-2%280%29=4 Plug in y=0.


x-0=4 Multiply -2 and 0 to get 0.


x=4 Simplify.


So the x-intercept is .


------------------------------------------


y-intercept


To find the y-intercept, plug in x=0 and solve for y


x-2y=4 Start with the given equation.


0-2y=4 Plug in x=0.


-2y=4 Simplify.


y=%284%29%2F%28-2%29 Divide both sides by -2 to isolate y.


y=-2 Reduce.


So the y-intercept is .


Now let's plot the points and which are the x and y intercepts respectively.





Now draw a straight line through the plotted points to graph x-2y=4.


Graph of x-2y=4
