**Reiny**, Saturday, December 11, 2010 at 10:23amDid you know that the slope of a line is the tangent of the angle that the line makes with the x-axis?

So they are telling us that the slope of the line is 1/3

so (y+5)/(x-12) = 1/3

cross-multiply and simplify if you want the actual equation of the line.
