I have tried subtracting -2x from both sides but its not right, please explain this to me. I need help asap as this is due tommorow morning. \n" ); document.write( "
Algebra.Com's Answer #270889 by scott8148(6628)![]() ![]() You can put this solution on YOUR website! the general slope-intercept form is ___ y = mx + b , where m is the slope and b is the y-intercept\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "in this case , the slope is -2 and the y-intercept is -3\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "graph by starting at a known point (the intercept) , -3 on the y-axis {coordinates (0,-3)}\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "generate the line using the slope of -2 \n" ); document.write( "___ this means that for every unit that x increases , y decreases 2 units (x and y change in opposite directions)\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "x = 1 , then y = -5 \n" ); document.write( "x = -1 , then y = -1 \n" ); document.write( "x = 3 , then y = -9 \n" ); document.write( "x = -4 , then y = 5 \n" ); document.write( " |
