Algebra.Com's Answer #256740 by Fombitz(32388)![]() ![]() You can put this solution on YOUR website! No, x and y are the variables. \n" ); document.write( "When \n" ); document.write( "(0,-2) \n" ); document.write( "Plot that point. \n" ); document.write( " \n" ); document.write( "Now you can do it one of two ways. \n" ); document.write( "Generate another point using the function or use the slope. \n" ); document.write( "To generate another point, pick another x. \n" ); document.write( "When \n" ); document.write( "(2,-4) \n" ); document.write( "Plot that point, connect the points with a line. \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( ". \n" ); document.write( ". \n" ); document.write( "The other way is to use the slope, \n" ); document.write( "In this case, \n" ); document.write( "THe slope is the change in y divided by the change in x. \n" ); document.write( "So if I move 1 unit in the x, then I move -1 units in the y. \n" ); document.write( "To get another point, start with the y-intercept, (0,-2). \n" ); document.write( "X: \n" ); document.write( "Y: \n" ); document.write( "(-1,-3) is another point on the line. \n" ); document.write( "Plot it and connect the points with a line. \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( ". \n" ); document.write( ". \n" ); document.write( "It's the same line. If I had moved 2 units in the x then I would have moved -2 units in the y (since \n" ); document.write( " \n" ); document.write( " |
