x-intercept


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


9x+%2B+3y+=+-13 Start with the given equation.


9x+%2B+3%280%29+=+-13 Plug in y=0.


9x+%2B+0+=+-13 Multiply 3 and 0 to get 0.


9x=-13 Multiply.


x=%28-13%29%2F%289%29 Divide both sides by 9 to isolate x.


So the x-intercept is .

y-intercept


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


9x+%2B+3y+=+-13 Start with the given equation.


9%280%29+%2B+3y+=+-13 Plug in x=0.


0+%2B+3y+=+-13 Multiply 9 and 0 to get 0.


y=%28-13%29%2F%283%29 Divide both sides by 3 to isolate y.


So the y-intercept is .
