Question 201403: Construct a table using at least five points on the graph of the equation x - 2y = 12
Solve the following problem; 120 yards of fencing is available to fence a triangular lot. If the triangular lot is a right triangle, and the length of one leg is x and the hypotenuse is 50 yards, find an expression for the area, A of the triangle as a function of x. Express your answer as a simplified quadratic expression.
The area of a triangle is given by 1/2base x height, => Area = ½b x h

For your first problem, just choose 5 different values for then substitute them one at a time for in the equation and calculate the value of that results.

If you have 120 yards of fencing available, then the perimeter of your triangular area must be 120 yards. One leg is and the hypotenuse is 50, so the length of the other leg is . Since it is a right triangle, either leg qualifies as a base of the triangle and then the other leg is the height, so:



All you have to do now is simplify it.
