Talk:Intermediate Algebra/Slope

This is in error on page http:en.wikibooks.org/wiki/Intermediate_Algebra/slope:

"But first we must find what the Y-Intercept is, to do this we choose one of the points that we are given, and input it into the formula. For this example, I'm going to use the point (4,3):

y(3) = m(1 / 2)x(4) + b 3 = 1 / 2(4) + b 3( + 2) = 2( − 2) + b 5 = B"

[Answer is 1 = B]

This is either a prank or careless error, but extremely confusing to students who find the page.

Then fix it.
