Find the equation of a straight line parallel to the line 2x - y = 5 and having intercept of 5
A.
2x + y = 5
B.
2x + y = -5
C.
2x - y = -5
D.
2x - y = 5
Correct Answer: 2x - y = -5
Explanation
Condition for Parallelism means that their gradient value is same line 2x - y = 5 is rearranged As y = 2x - 5 from y = mx + c : line 2x - y = 5 has the gradient of 2 A parallel line with gradient of 2 and intercept of 5 → 2x - y = -5 Rearranged as y = 2x + 5
