Problem 5 Got It? The office manager of a small office ordered 140 packs of printer paper. Based on average daily use, she know that the paper will last about 80 days.

What graph represents this situation? Zoom and pan your graph to leave an appropriate scale and viewing window.

Graphing: What are the intercepts of 3x + y = 6? Graph the equation. Be sure to include relevant graph detail: label axes, indicate units and scale on both axes, and use arrows to represent end behavior, as appropriate.

Understanding: Which form would you use to write the equation of a line if you knew its slope and x-intercept? Explain.

Understanding: If the intercepts of a line are (a, 0) and (0, b), what is the slope of the line?
