- A. y = −2x + 1
- B. y = 2x + 7
- C. y = −2x − 1
- D. y = −½x + 2
Verified working — step 1
Parallel lines share a gradient - and with a negative point, guard the signs: x - (-2) is x + 2.The full step-by-step working and final answer are included with Premium — checked against ECZ marking standards.
