9%2Ax-4%2Ay=-36 Start with the given equation

Let's find the x-intercept

To find the x-intercept, let y=0 and solve for x:
9%2Ax-4%2A%280%29=-36 Plug in y=0

9%2Ax=-36 Simplify

x=-36%2F9 Divide both sides by 9


x=-4 Reduce



So the x-intercept is (note: the x-intercept will always have a y-coordinate equal to zero)

9%2Ax-4%2Ay=-36 Start with the given equation

Now let's find the y-intercept

To find the y-intercept, let x=0 and solve for y:
9%2A%280%29-4%2Ay=-36 Plug in x=0

4%2Ay=-36 Simplify

x=-36%2F-4 Divide both sides by -4



y=9 Reduce



So the y-intercept is (note: the y-intercept will always have a x-coordinate equal to zero)

So we have these intercepts:
