For the straight line defined by the points (3, 51) and (5, 87), determine the slope and y-intercept.
\n" ); document.write( "----------
\n" ); document.write( "slope = (87-51)/(5-3) = 36/2 = 18
\n" ); document.write( "----------
\n" ); document.write( "Form: y = mx + b
\n" ); document.write( "y-intercept::
\n" ); document.write( "Substitute fr y,m,x to solve for \"b\":
\n" ); document.write( "87 = 18*5 + b
\n" ); document.write( "b = 87-90
\n" ); document.write( "b = -3
\n" ); document.write( "--------
\n" ); document.write( "Equation:
\n" ); document.write( "y = 18x - 3
