Algebra.Com's Answer #408325 by Shana-D77(132)![]() ![]() You can put this solution on YOUR website! When you're given a slope and a point, it's best to use the point-slope form of the equation. \"The\" equation means the linear (straight line) equation. The point slope form is: \n" ); document.write( " \n" ); document.write( "y = y1 = m(x - x1). \n" ); document.write( "((side note: this is actually the slope formula, just rearranged.)) \n" ); document.write( " \n" ); document.write( "So, \n" ); document.write( " \n" ); document.write( "slope (m) = -7 \n" ); document.write( " point (7, 4) \n" ); document.write( " \n" ); document.write( "y - y1 = m(x - x1) \n" ); document.write( "(the y and the x always stay as y and x in this form) \n" ); document.write( " \n" ); document.write( "Plug in what your teacher gave you. y1 = 4 and x1 = 7 (from (7,4)), and slope (m) = -7 \n" ); document.write( " \n" ); document.write( " y - 4 = -7(x - 7) \n" ); document.write( "y - 4 = -7x + 49 (distributed the -7) \n" ); document.write( "y = -7x + 53 (added 4 to both sides) \n" ); document.write( " \n" ); document.write( " |
