You can put this solution on YOUR website!
The slope-intercept formula is
\n" ); document.write( "y=mx+b
\n" ); document.write( ".
\n" ); document.write( "First you have to find your slope
\n" ); document.write( "The slope, m, of the line is the change in y divided by the change in x.
\n" ); document.write( ".
\n" ); document.write( "m = (y2-y1) / (x2-x1)
\n" ); document.write( "x1= -6.2 ; y1= 18.1
\n" ); document.write( "x2= 3.4 ; y2= 18.1
\n" ); document.write( ".
\n" ); document.write( "m= (18.1-18.1) / (3.4- -6.2)
\n" ); document.write( "m= 0 / 9.6
\n" ); document.write( "m= 0
\n" ); document.write( ".
\n" ); document.write( "If your slope would have 9.6 / 0 the slope would have been undefined and it would have been a vertical line, but since it's a slope of zero it's going to be a horizontal line.
\n" ); document.write( ".
\n" ); document.write( "Now, to find the y-intercept, b, use one of the points to get the x and y values, and solve for b.
\n" ); document.write( ".
\n" ); document.write( "y1 = mx1 + b
\n" ); document.write( "b = y1 - mx1
\n" ); document.write( ".
\n" ); document.write( "b = 18.1 - 0(-6.2)
\n" ); document.write( "b = 18.1\r
\n" ); document.write( "\n" ); document.write( "So your equation is :
\n" ); document.write( "y = 18.1
\n" ); document.write( ".
\n" ); document.write( "Your graph will just be a horizontal line at 18.1. \r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
