Visualizing Maintenance Cost Trends

As a facility manager, you use the linear equation y=4x2y = 4x - 2 to model the total maintenance cost (yy) over time in hours (xx). To prepare a training manual for your team, describe the step-by-step procedure for graphing this equation using the slope and y-intercept method. Your explanation must include the identification of the slope and y-intercept, the coordinates of the starting point, the specific 'rise' and 'run' used to find a second point, and the final coordinates of that second point.
