Question 269085: please help my solve this equation
this is what my homework said
find the intercepts of the equations graph.then graph the equation on the given coordinate grid.
2x+ y=-2
and then it has a x and y graph
Thanks a lot

x-intercept


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


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


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


2x%2B+0=-2 Simplify.


2x=-2 Multiply.


x=%28-2%29%2F%282%29 Divide both sides by 2 to isolate x.


x=-1 Reduce.


So the x-intercept is .


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


y-intercept


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


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


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


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


+y=-2 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%2B+y=-2.


Graph of 2x%2B+y=-2
