You can put this solution on YOUR website!
You can use desmos.com, choose the Graphing Calculator tool, within that from the PLUS symbol at upper left, make a table for each of your sets of linear data points. Click the switch in each for \"Line\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "You can then read the slope and y intercept of each of the two lines and write in slope-intercept form. From those, change each equation into the Ax+By=C form; and make your answer selection.\r
