**Henry**, Thursday, July 15, 2010 at 8:44pmGIVEN: ( 4, 3 ), ( 10, 0 ).

m = -3/6 = -1/2 = -0.5

Find Equation of line:

Y = mX + b

3 = -1/2(4) + b.

Solve for b: b = 5.

Y = -1/2X +5

Substitute 6 for Y and solve for X.

6 = -1/2X + 5

1/2X = -1, X = -2. P ( -2, 6 ) is

where the lines intersect. Y = 6 is

a horizontal line 6 units above x

axis. Graph both lines and compare

point of intersection ( solution )

with calculated value.
