How do you solve the following linear system: #y=-x+4, 3x+y=-2#?
This is one of the best forms you can have for a system of equations. Note that they each have a single
Graphically it means they each represent a straight line and the solution is the point of intersection of the lines.
Write each equation in slope-intercept form, ie with
Now you can use one equation to find a value for
other equation to check.
