Find an equation of the line that satisfies the given conditions.
\n" ); document.write( "through (8, 1); parallel to the line passing through (9, -1) and (-4, -5)
\n" ); document.write( "--------------------------
\n" ); document.write( "1st: Find the slope
\n" ); document.write( "m = (-5--1)/(-4-9) = -4/-13 = 4/13
\n" ); document.write( "---------------------
\n" ); document.write( "Form: y = mx + b
\n" ); document.write( "You know y = 1 when x = 8, and m = 4/13; solve for \"b\":
\n" ); document.write( "1 = (4/13)8 + b
\n" ); document.write( "1 = 32/13 + b
\n" ); document.write( "b = (13/13)-(32/13)
\n" ); document.write( "b = -19/13
\n" ); document.write( "-------------------------------
\n" ); document.write( "Equation:
\n" ); document.write( "y = (4/13)x - (19/13)
\n" ); document.write( "==============================\r
