Identify Slope and Y-Intercept: question_prompt: What is the graph of the line with the equation y=−(21)x−2?
Plot Y-Intercept: To graph the line, we need to identify the slope and y-intercept from the equation.
Use Slope to Find Second Point: The slope is the coefficient of x, which is −(21), and the y-intercept is the constant term, which is −2.
Plot Second Point and Draw Line: Start by plotting the y-intercept (0,−2) on the graph.
Plot Second Point and Draw Line: Start by plotting the y-intercept (0,−2) on the graph. From the y-intercept, use the slope to find another point. Since the slope is −(21), go down 1 unit and right 2 units from the y-intercept.
Plot Second Point and Draw Line: Start by plotting the y-intercept (0,−2) on the graph. From the y-intercept, use the slope to find another point. Since the slope is −(21), go down 1 unit and right 2 units from the y-intercept. Plot the second point and draw a straight line through the two points. This is the graph of the line.
