Algebra.Com's Answer #750836 by addingup(3677)![]() ![]() You can put this solution on YOUR website! y = mx + b \n" ); document.write( "Where: m is the slope, and b is the y-intercept \n" ); document.write( "Since m (slope) is given, we can start filling in the equation: \n" ); document.write( "y = -5/2x + b \n" ); document.write( "~~~~~~~~~~~~~~~~~~~~~~~~~~~~ \n" ); document.write( "Next, we have the point (2,9) that says when x of the line is 2, y is 9 \n" ); document.write( "(2,9): y = mx + b, substitute: \n" ); document.write( "9 = -5/2(2) + b \n" ); document.write( "Solve for b: \n" ); document.write( "9 = -5 + b \n" ); document.write( "b = 14 \n" ); document.write( "~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ \n" ); document.write( "So now we fill in the numbers: \n" ); document.write( "y = mx + b \n" ); document.write( "9 = -5/2(2) + 14 \n" ); document.write( " \n" ); document.write( " |
