Find the slope of line AC, and determine the slope for a line perpendicular to it.
Use point slope form of equation to make the equation of line with that slope and containing B(2,3).

AC has slope .
Slope needed will be for the perpendicular line containing B.
-----your line containing the altitude through B. Adjust to the form you want.
