Algebra.Com's Answer #141578 by nerdybill(7384)![]() ![]() You can put this solution on YOUR website! write the slope intercept of the line ( 7,-10) slope -3/4. \n" ); document.write( ". \n" ); document.write( "The \"slope intercept\" form of a line is \n" ); document.write( "y = mx + b \n" ); document.write( "where \n" ); document.write( "m is slope \n" ); document.write( "b is the y-intercept \n" ); document.write( "(x,y) are points along that line \n" ); document.write( ". \n" ); document.write( "Your problem gives you: \n" ); document.write( "one point: at ( 7,-10) \n" ); document.write( "m = -3/4 \n" ); document.write( "Simply plug in the above and solve for b: \n" ); document.write( "y = mx + b \n" ); document.write( "-10 = (-3/4)(7) + b \n" ); document.write( "-40 = (-3)(7) + 4b \n" ); document.write( "-40 = (-21) + 4b \n" ); document.write( "-19 = 4b \n" ); document.write( "-19/4 = b \n" ); document.write( ". \n" ); document.write( "Our equation is then: \n" ); document.write( "y = (-3/4)x - 19/4 (this is what they're looking for) \n" ); document.write( " |
