Algebra.Com's Answer #365811 by Leaf W.(135)![]() ![]() You can put this solution on YOUR website! Plug your information into point-slope form, where x1 is your value for x (2) and y1 is your value for y (-9). \n" ); document.write( "y - y1 = m(x - x1) \n" ); document.write( "Put in your values for m, x1, and y1: \n" ); document.write( "Change -(-9) to +9 and distribute the \n" ); document.write( "Clear fractions by multiplying everything by 9: 9y + 81 = 8x - 16 \n" ); document.write( "Subtract 81 from both sides of the equation: 9y = 8x - 97 \n" ); document.write( "Now which format do you need your answer to be in--standard (ax + by = c) or slope-intercept (y = mx + b)? \n" ); document.write( "==> Standard: \n" ); document.write( "Subtract 8x from both sides of the equation: -8x + 9y = -97 \n" ); document.write( "Multiply everything by -1 (so that the coefficient before a is positive): 8x - 9y = 97 <--YOUR ANSWER \n" ); document.write( "==> Slope-intercept: \n" ); document.write( "Divide everything by 9 (so that y has no coefficient): \n" ); document.write( "Good luck! =) \n" ); document.write( " |
