Question

An equation is shown.

y = −13x −1

Which graph represents this equation?

Answer 1

Look for the straight line with y‑intercept (0, −1) and a very steep negative slope (drop 13 units for each 1 unit right). Key points: (0, −1), (1, −14), and (−1, 12). The correct graph is the line through (0, −1) slanting sharply down to the right.
