x-intercept


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


x%2B4y=8 Start with the given equation.


x%2B4%280%29=8 Plug in y=0.


x%2B0=8 Multiply 4 and 0 to get 0.


x=8 Simplify.


So the x-intercept is .


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


y-intercept


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


x%2B4y=8 Start with the given equation.


0%2B4y=8 Plug in x=0.


4y=8 Simplify.


y=%288%29%2F%284%29 Divide both sides by 4 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%2B4y=8.
