Points in the solution region are (2.8, -1.4) and (-8, 4). Points outside the solution region are (-1.6, 1.8) and (-2, -5).

.(-1.6, 1.8): -1.6 + 2 ✕ 1.8 = 2

. ➞This does not materialize. (-2, -5): -2 + 2 ✕ (-5) = -12

(-2)2+ (-5) = -1

. ➞This does not materialize. (2.8, -1.4): 2.8 + 2 ✕ (-1.4) = 0 (2.8)2 + (-1.4) = 6.44

. ➞This materializes. (-8, 4): -8 + 2 ✕ 4 = 0

(-8)2+ 4 = 68

➞This materializes.

Graphical solution methods not only offer instructive visualization of the solution process, but they can be applied to inequalities that are often very difficult to solve algebraically. The EL-9650/9600c/9450/9400 allows the solution region to be indicated visually using the Shading feature. Also, the free-moving tracer or Zoom-in feature will allow the details to be checked visually.
