a straight line with slope -5 contains the point (1, 2). What is the area of the triangle formed by this line and the x- and y-axes?
==============
Find the eqn of the line.
y - 2 = -5(x-1)
y = -5x + 7
Find the x & y intercepts.
y-int = A(0,7)
x-int = B(1.4,0)
==========
Area = A*B/2
Area = 4.9 sq units
