x-intercept


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


x%2By=4 Start with the given equation.


x%2B0=4 Plug in y=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%2By=4 Start with the given equation.


0%2By=4 Plug in x=0.


y=4 Simplify.


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%2By=4.
