How do you solve the system of equations by graphing #y=3x-2#, #x+y=-6#?
The common value are
Changing the form of equation (2) so that it matches eqn type
So now we have both equations in standard form
Make a table of values that outputs the value of
Plot your points and draw lines through them extended to the edge of the squares.
Mark your points and label each line to show which equation it represents.
The point where the two lines cross is the solution. ie the x value and the y value
If all three points for any one of the lines do not line up then your point calculations are wrong some where.
