x-intercept


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


2x-y=18 Start with the given equation.


2x-0=18 Plug in y=0.


2x=18 Simplify.


x=%2818%29%2F%282%29 Divide both sides by 2 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


2x-y=18 Start with the given equation.


2%280%29-y=18 Plug in x=0.


0-y=18 Multiply 2 and 0 to get 0.


-y=18 Simplify.


y=%2818%29%2F%28-1%29 Divide both sides by -1 to isolate y.


y=-18 Reduce.


So the y-intercept is .


Now let's plot the points and which are the x and y intercepts respectively.





Now draw a straight line through the plotted points to graph 2x-y=18.
