Q. Graph this line using the slope and y y -intercept:\newliney=9x−7 y=9 x-7 \newlineClick to select points on the graph.
  1. Identify slope and y-intercept: Identify the slope (mm) and y-intercept (bb) from the equation y=9x−7y=9x-7. Slope m=9m=9 and y-intercept b=−7b=-7.
  2. Plot y-intercept: Plot the y-intercept on the graph at the point (0,−7)(0, -7).
  3. Use slope to find another point: Use the slope to find another point. Since the slope is 99, it means rise over run is 91\frac{9}{1}. From the y-intercept, go up 99 units and 11 unit to the right to find the next point.
  4. Plot second point: Plot the second point at (1,2)(1, 2). Oops, made a mistake here. The second point should be at (1,2+7)(1, 2+7) which is (1,9)(1, 9) because we start at −7-7 on the y-axis and go up 99 units.
