To graph x+4y=8, all we need are two points.

So let's find the x and y intercepts and those will be our two points.

x-intercept

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

Start with the given equation.

Plug in .

Multiply and 0 to get 0.

Simplify.

So the x-intercept is

.

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

y-intercept

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

Start with the given equation.

Plug in .

Simplify.

Divide both sides by to isolate .

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 .

Graph of
