which equation describes a line that passes through the points (3,5) and (2,-3) (I'll assume you had a typo in the second point)
\n" ); document.write( ".
\n" ); document.write( "First, determine the slope:
\n" ); document.write( "m = (y2-y1)/(x2-x1)
\n" ); document.write( "m = (-3-5)/(2-3)
\n" ); document.write( "m = (-8)/(-1)
\n" ); document.write( "m = 8
\n" ); document.write( ".
\n" ); document.write( "Then using the slope above and one of the two given points (3,5) plug into the \"point-slope\" form:
\n" ); document.write( "y - y1 = m(x - x1)
\n" ); document.write( "y - 5 = 8(x - 3)
\n" ); document.write( "y - 5 = 8x - 24
\n" ); document.write( "y = 8x - 19 (this is what they're looking for)\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
