Express the equation in intercept form: x%2F-15%2By%2F9+=+1. (Divide both sides by -45!) Then the x-intercept is (-15,0), and the y-intercept is (0, 9).

x-intercept


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


3x-5y=-45 Start with the given equation.


3x-5%280%29=-45 Plug in y=0.


3x-0=-45 Multiply -5 and 0 to get 0.


3x=-45 Simplify.


x=%28-45%29%2F%283%29 Divide both sides by 3 to isolate x.


x=-15 Reduce.


So the x-intercept is .

y-intercept


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


3x-5y=-45 Start with the given equation.


3%280%29-5y=-45 Plug in x=0.


0-5y=-45 Multiply 3 and 0 to get 0.


-5y=-45 Simplify.


y=%28-45%29%2F%28-5%29 Divide both sides by -5 to isolate y.


y=9 Reduce.


So the y-intercept is .
