I can't see the four graphs — could you upload the image or describe where each student placed the point?
Meanwhile, here’s how to quickly tell which graph is correct:
- The point (−174, −2.5) has x negative and y negative, so it must lie in the lower‑left quadrant (Quadrant III).
- From the origin, move 174 units to the left along the x‑axis, then 2.5 units down. If the axes use a different scale, move 174 of those x‑units left and 2.5 of those y‑units down (e.g., if each tick = 10, move 17.4 ticks left and 0.25 ticks down).
- Common mistakes to watch for:
- Swapped coordinates (plotted (−2.5, −174) instead).
- Wrong signs (plotted positive x or positive y).
- Using the wrong scale (plotting too close to the origin if 174 units weren’t accounted for).
If you upload the picture I’ll point out exactly which student is correct.
