Algebra.Com's Answer #46921 by ankor@dixie-net.com(22740)![]() ![]() You can put this solution on YOUR website! Which statement describes the change to the graph of f(x)=3x+2 when f(x)=-(1/3x)+1 is graphed? \n" ); document.write( ": \n" ); document.write( "No doubt you strongly suspect that a slope of 3 would be perpendicular to a slope of -1/3. \n" ); document.write( "You can prove that: slope1*slope2 = -1 when lines are perpendicular \n" ); document.write( "3*-(1/3) = -1, so we know that it will be choice A) or C) \n" ); document.write( ": \n" ); document.write( "y intercept occurs when x = 0, therefore 3x+2 has a y intercept of 2 and \n" ); document.write( "-1/3x + 1 has a y intercept of 1, proving that A) is the choice.\r \n" ); document.write( "\n" ); document.write( "Answer Choices: \n" ); document.write( "A) The y-intercept changes from 2 to 1, and the new graph is perpendicular to the original graph. \n" ); document.write( "B) The graph of the line moves left 1 unit, and the slope changes from 3 to \n" ); document.write( "-(1/3) \n" ); document.write( "C) The graphs of the lines are perependicular and meet at their y-intercepts. \n" ); document.write( "D) The graph of the line moves left 1 unit and down 3 units. \n" ); document.write( " |
