Algebra.Com's Answer #87857 by bucky(2189) ![]() You can put this solution on YOUR website! The slope-intercept form of an equation is: \n" ); document.write( ". \n" ); document.write( "y = mx + b \n" ); document.write( ". \n" ); document.write( "in which m, the multiplier of x, is the slope and b, a constant, is the y-intercept. \n" ); document.write( ". \n" ); document.write( "The equation you are given is y = (-2/3)x + 20 and you can see by inspection that this equation \n" ); document.write( "is in the slope-intercept form. By comparing this equation with the slope-intercept \n" ); document.write( "form, you can see that the multiplier of the x is -2/3 so the slope of the line of the given \n" ); document.write( "equation is -2/3. You can also see by this comparison that the constant term is +20, and \n" ); document.write( "so the y-intercept is +20. \n" ); document.write( ". \n" ); document.write( "So the answer to you problem is slope = -2/3 and y-intercept = +20 ... both of which you \n" ); document.write( "can immediately identify by inspection. \n" ); document.write( ". \n" ); document.write( "Hope this helps you to understand the problem. \n" ); document.write( ". \n" ); document.write( " |
