x-intercept


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


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


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


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


-x+=+-9 Simplify.


x=%28-9%29%2F%28-1%29 Divide both sides by -1 to isolate x.


x=9 Reduce.


So the x-intercept is .


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


y-intercept


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


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


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


+3y+=+-9 Simplify.


y=%28-9%29%2F%283%29 Divide both sides by 3 to isolate y.


y=-3 Reduce.


So the y-intercept is .


Now plot the points we just found





Now draw a line through those two points to graph the equation -x+%2B+3y+=+-9



Graph of -x+%2B+3y+=+-9 with the x-intercept of (9,0) and the y-intercept of (0, -3)
