3%2Ax-5%2Ay=9 Start with the given equation

Let's find the x-intercept

To find the x-intercept, let y=0 and solve for x:
3%2Ax-5%2A%280%29=9 Plug in y=0

3%2Ax=9 Simplify

x=9%2F3 Divide both sides by 3


x=3 Reduce



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

3%2Ax-5%2Ay=9 Start with the given equation

Now let's find the y-intercept

To find the y-intercept, let x=0 and solve for y:
3%2A%280%29-5%2Ay=9 Plug in x=0

-5%2Ay=9 Simplify

x=9%2F-5 Divide both sides by -5



y=-9%2F5 Reduce



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

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

So we have these intercepts:
x-intercept:

y-intercept:
