Solve the system of linear equations by graphing
4x+y = 0
3x + y = 2
----------------
Linear equations' graphs are straight lines, so you need 2 points.
4x+y = 0
y = -4x
Pick 2 values for x and find y, any 2
x = 0, y = 0 --> (0,0)
x = 2, y = -8 --> (2,-8)
Plot the 2 points, draw a line thru them.
----------
3x + y = 2
y = -3x + 2
Do the same.
Where they intersect is the solution to the system, x & y values that fit both equations.
