Algebra.Com's Answer #133925 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! A line has a slope of 7. Use the slope formula to find the missing coordinate \n" ); document.write( "(x,8) (4,1) \n" ); document.write( "x=5 but when I try to use the slope formula I am making a mistake somewhere. \n" ); document.write( "----------------- \n" ); document.write( "If slope = 7 and (4,1) is a point, \n" ); document.write( "the intercept is b where 1 = 7*4 + b; b = -27 \n" ); document.write( "--- \n" ); document.write( "Equation: y = 7x - 27 \n" ); document.write( "-------------------------- \n" ); document.write( "So, if y = 8, 8 = 7x - 27; 7x = 35; x = 5 \n" ); document.write( "============================================ \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
