How do you solve the system #x + y - 6 = 0# and #x - y = 0# by graphing?
Draw the lines for the linear equations given and note the point at which the two line insect (in this case at
The easiest points to use for graphing purposes are often the intercepts.
the intercepts are at
the x and y-intercepts are the same point:
so it will be necessary to pick one more point;
since we already have a
Drawing a line connecting
and another connecting
gives us a point of intersection at
