Graph the following equations; calculate the slope, xintercept, and yintercept, and label the intercepts on the graph.
Find the area of a rectangle if three of its corners are (0.1,3.4), (7.9,3.4), and (0.1,6.8).

A(7.9, 3.4), B(0.1, 3.4).
b=hor. = 0.1(7.9) = 7.8 = The Base.
B(0.1, 3.4), C(0.1, 6.8),
h=ver.=6.8(3.4) = 10.2 = The height.
A = bh = 7.8 * 10.2 = 79.6
