Sketch the graph of the equation y=-1. please show all your work thank you so much! the chapter is exploring graphs of linear equations and the text book is Passport to Algebra and Geometry. \n" ); document.write( "
Algebra.Com's Answer #146850 by vleith(2983)![]() ![]() ![]() You can put this solution on YOUR website! Most of the time you are asked to graph a line, that equation will have two variables in it (x and y). In this case, there is only one variable (y).\r \n" ); document.write( "\n" ); document.write( "What this equation is telling you is 'no matter what value I pick you x, the value for y is always -1'.\r \n" ); document.write( "\n" ); document.write( "If you plot any two points with the y coordinate = -1, you can quickly see that the line containing those points is a horizontal line that runs through the point (0, -1).\r \n" ); document.write( "\n" ); document.write( "For a nice tool to help with this type of plotting, go get geogebra.
