Algebra.Com's Answer #303611 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! A line passes through (–10, 5) and (–9, 10). \n" ); document.write( "a. Write an equation for the line in point-slope form. \n" ); document.write( "slope = (10-5)/(-9--10) = 5/1 = 5 \n" ); document.write( "--- \n" ); document.write( "Form: y = mx + b \n" ); document.write( "You know y = 5 when x = -10 and you knoe m = 5. \n" ); document.write( "So solve for \"b\": \n" ); document.write( "5 = 5(-10)+b \n" ); document.write( "b = 55 \n" ); document.write( "Equation: \n" ); document.write( "y = 5x+55 \n" ); document.write( "------------------------------ \n" ); document.write( "b. Rewrite the equation in standard form using integers. \n" ); document.write( "Standard form: ax + by = c \n" ); document.write( "5x -y = -55 \n" ); document.write( "================== \n" ); document.write( "cheers, \n" ); document.write( "Stan H. \n" ); document.write( " \n" ); document.write( " |
