-15%2Ax%2B1%2Ay=55 Start with the given equation

Let's find the x-intercept

To find the x-intercept, let y=0 and solve for x:
-15%2Ax%2B1%2A%280%29=55 Plug in y=0

-15%2Ax=55 Simplify

x=55%2F-15 Divide both sides by -15


x=-11%2F3 Reduce



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

-15%2Ax%2B1%2Ay=55 Start with the given equation

Now let's find the y-intercept

To find the y-intercept, let x=0 and solve for y:
-15%2A%280%29%2B1%2Ay=55 Plug in x=0

-1%2Ay=55 Simplify

x=55%2F1 Divide both sides by 1



y=55 Reduce



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

So we have these intercepts:
