Date ____________
Consistent and Independent, Consistent and Dependent, Inconsistent
Ex 1| Solve by graphing
y  2x
y  x  3
1. Are the equations in y = mx + b form?
2. Pull out your slope and y-intercept for each equation.
3. Graph each equation on the same set of axes using the slope and yintercept.
4. Look for the point where both graphs intersect.
