Question 839886: I am really having trouble with understanding how to graph each pair of equations and how to state the solution of each system of equation.. Can you please show me how to do this and explain how you did it??
x+y=-6
2x+y=4

You can put this solution on YOUR website!
To graph a line choose two points.
You can choose two x, two y, or one x and one y.
Use the equation to solve for the unknown.
Let x=0, solve for y
x%2By=-6
0%2By=-6
y=-6
(0,-6)
Let y=0, solve for x
x%2By=-6
x%2B0=-6
x=-6
(-6,0)
Plot the points.

Draw the line.

Similarly for 2x%2By=4
(0,4) and (2,0)
Now plot the points and connect them with a line.

Where the two lines intersect is the solution for the system of equations.
