Algebra.Com's Answer #34182 by darq(90)![]() ![]() You can put this solution on YOUR website! slope intercept form = y = mx+b\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "b is y intercept so we need to find the y value when x is 0. substitute the (-3,0) with (x,y) in the slope intercept form.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "y = mx+b \n" ); document.write( "0 = m*-3+b \n" ); document.write( "we know that slope is negative 3. \n" ); document.write( "0 = -3*-3+b \n" ); document.write( "0 = 9+b \n" ); document.write( "b= -9\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "so substitute m and b values with m and b in the slope intercept form.\r \n" ); document.write( "\n" ); document.write( "y=-3x+(-9) \n" ); document.write( "y=-3x-9 \n" ); document.write( " |
