Answer:
To graph a line with a slope of -2 that goes through the point (2, 1), begin by plotting the point (2, 1). Then, using the slope, choose any other point along the line. To find this point, use the slope formula to find the change in y over the change in x, or y2-y1/x2-x1 = -2. Since the x coordinate is 2, any point with an x coordinate of 3 will have a y coordinate of -1. Plot the point (3, -1). Then, draw a line connecting the two points. The line will have a slope of -2.
Explanation:
To graph a line that goes through the points (2, 1) and has a slope of -2, draw a line on a coordinate plane that has the point (2, 1) as one of its points. From this point, draw a line that has a slope of -2 (means that for every 2 units the line moves horizontally, it moves 1 unit vertically). The result should be a line that goes through the point (2, 1) and has a slope of -2.
