Algebra.Com's Answer #177760 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! Determine the equation of the line described. Put answer in the slope-intercept form, if possible. Through (1,-8), perpendicular to -7x-4y=25. \n" ); document.write( "-------------- \n" ); document.write( "The given line has slope = -7/4 \n" ); document.write( "------------------------------------ \n" ); document.write( "A perpendicular line must have slope = 4/7 \n" ); document.write( "------------------------ \n" ); document.write( "Form: y = mx + b \n" ); document.write( "m = 4/7 and y = -8 when x = 1 \n" ); document.write( "Solve for \"b\": \n" ); document.write( "-8 = (4/7)*1 + b \n" ); document.write( "b = -60/7 \n" ); document.write( "-------------------------- \n" ); document.write( "y = (4/7)x-(60/7) \n" ); document.write( "--- \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
