Graphing y=−x−3y = -x - 3 Using its Slope and y-Intercept

To graph the linear equation y=−x−3y = -x - 3 using its slope and y-intercept, start by identifying the slope and y-intercept directly from the slope-intercept form (y=mx+by = mx + b). The slope is m=−1m = -1, which translates to a rise of −1-1 and a run of 11. The y-intercept is the constant term, giving the coordinate point (0,−3)(0, -3). Plot the y-intercept (0,−3)(0, -3) on the coordinate plane. Then, apply the slope by counting down 11 unit and right 11 unit to locate a second point at (1,−4)(1, -4). Draw a straight line connecting these points to complete the graph.
