Question 655519: The promblem says given -2x+y=-4 find the x and y intercept then graph the solution?
I know how to figure out the x and y intercept but im not understanding what is it they want me to graph ( do I need to find points)

x-intercept


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


-2x%2By=-4 Start with the given equation.


-2x%2B0=-4 Plug in y=0.


-2x=-4 Simplify.


x=%28-4%29%2F%28-2%29 Divide both sides by -2 to isolate x.


x=2 Reduce.


So the x-intercept is .


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


y-intercept


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


-2x%2By=-4 Start with the given equation.


-2%280%29%2By=-4 Plug in x=0.


-0%2By=-4 Multiply -2 and 0 to get 0.


y=-4 Simplify.


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%2By=-4.
