Algebra.Com's Answer #579804 by macston(5194)![]() ![]() You can put this solution on YOUR website! 2x-y=4 Put in slope intercept form:y=mx+b: Add y to each side \n" ); document.write( "2x=4+y Subtract 4 from each side \n" ); document.write( "2x-4=y Our slope (m) must be the same for a parallel line \n" ); document.write( "y=2x+b We are given an x and y for our line: (-3,-11} \n" ); document.write( "-11=2(-3)+ b \n" ); document.write( "-11=-6 + b Add 6 to each side. \n" ); document.write( "-5=b \n" ); document.write( "So m=2, and b=-5 \n" ); document.write( "y=mx+b \n" ); document.write( "y=2x-5 ANSWER Equation for the parallel line through (-3,-11) is y=2x-5 (or 2x-y=5). \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " |
