Equations and inequalities describe the relationship between two mathematical expressions.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.

2. Shania is fishing from a small boat. A fish swimming at the same depth as the hook at the end of her fishing line is 8 meters away from the hook. If Shania is 10 meters away from the fish, how far below Shania is the hook? Shania is 10 M away from the fish, and the fish is 8 M away from the hook.
3. A rectangular room has dimensions 12x12x24. That is, the floor and ceiling and both the side walls are 12x24 and the two end walls are 12x12. In the room there are two ants, a male and a female. The male ant is on the floor at one of the corners. Now the female has positioned herself to be as far as possible from the male. That is, she has located herself at a point so that the male will take the longest possible time to get to her, given that he has to craw! along the walls, floor or ceiling of the room and will (of course) choose his path so that he gets to the female in the shortest possible time. • F The question is: where is the female? Well there's an obvious answer-the diametrically opposite corner. That's certainly the point which is farthest from the ant "as the crow flies." But an ant is not a crow.
