Documenting the Graphing Procedure for Cost Estimation

You are working as an assistant project coordinator for a construction firm. Your team uses the linear equation y=32x+10y = \frac{3}{2}x + 10 to estimate the total cost (yy, in thousands of dollars) based on the number of weeks (xx) a specialized piece of equipment is rented for a job site. Your supervisor has asked you to write a brief technical guide for the junior staff explaining how to graph this cost model.

In your response, describe the standard six-step procedure to graph this specific line using only its slope and y-intercept. Your explanation should clearly list each action in the correct order, from identifying the components of the given equation to drawing the final line on a coordinate plane.
