You can put this solution on YOUR website!
the slope intercept form of the equation of a straight line is:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "y = mx + b\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "m is the slope
\n" ); document.write( "b is the y-intercept.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "if your know the slope, then just replace m with it and solve for b by replacing x and y in the equation with the value of one of the points.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "in your problem, m = 3/4 and the point that it goes through is (x,y) = (5,-4)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "replace m with 3/4 and replace x with 5 and y with -4 to get:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "y = mx + b becomes -4 = 3/4 * 5 + b\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "simplify to get:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "-4 = 3.75 + b\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "subtract 3.75 from both sides of the equation to get:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "-4 - 3.75 = b\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "solve for b to get:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "b = -7.75\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the equation becomes:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "y = 3/4 * x - 7.7 5\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the graph of the equation looks like this.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "you can see that the y-intercept (the value of y when x = 0) is -7.75 and that the graph of the equation goes through the point (x,y) = (5,-4).\r
