Algebra.Com's Answer #180326 by nerdybill(7384)![]() ![]() You can put this solution on YOUR website! Write the equation of the line that goes through the point (1,3) and is parallel to the line y=-3x+3/5. Write your equation in slope-intercept form. \n" ); document.write( ". \n" ); document.write( "A line parallel to y=-3x+3/5 MUST have the same slope. \n" ); document.write( "Since y=-3x+3/5 is in \"slope-intercept\" form, by inspection we see that our NEW line has a slope of -3. \n" ); document.write( ". \n" ); document.write( "Plug -3 (slope) and the given point (1,3) into the \"point-slope\" form: \n" ); document.write( "y - y1 = m(x-x1) \n" ); document.write( "y - 3 = -3(x-1) \n" ); document.write( "y - 3 = -3x+1 \n" ); document.write( "y = -3x+4 (this is what they're looking for)\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
