Algebra.Com's Answer #533342 by josgarithmetic(39618)![]() ![]() ![]() You can put this solution on YOUR website! That equation is in point-slope form. This form shows you the slope and a point on the line.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Assuming you know and understand the formula for slope of a line, you could have a variable point (x, y) and a known given point (u, v).
