Graphing y=x1y = -x - 1 Using its Slope and y-Intercept

To graph the linear equation y=x1y = -x - 1 using its slope and y-intercept, first identify the slope and y-intercept from the equation, which is already in y=mx+by = mx + b form. The slope is m=1m = -1, giving a rise of 1-1 and a run of 11. The y-intercept is the point (0,1)(0, -1). Plot (0,1)(0, -1) on a rectangular coordinate system. From this point, count the slope by moving down 11 unit and right 11 unit to mark a second point at (1,2)(1, -2). Draw a straight line through these points to finish graphing the equation.
