I don't have the graph or any other info about line q, so I can't pick the right choice yet. Can you upload the diagram or tell me one of these about line q?
- a point it goes through (e.g. (2,3))
- its slope
- whether it's parallel or perpendicular to some given line
Quick help to use the four choices:
- Two choices have slope −2 (y = −2x + 5 and y = −2x − 5) — those are lines parallel to any line with slope −2; the +5/−5 is the y‑intercept.
- Two choices have slope 0.5 (y = 0.5x + 7.5 and y = 0.5x − 7.5) — those are perpendicular to slope −2 (0.5 = −1/(−2)); again the ±7.5 are the y‑intercepts.
If you tell me one point on q or whether it’s parallel/perpendicular to a known line (and its intercept), I’ll pick the correct equation.
