Question

Which of the following is the equation of a line passing through the origin and parallel to the line 2x – y = 5?

a. 5x – y = 0
b. 2x – y = 0
c. 2x + y = 5
d. 2x + y = 0
e. x + 2y = 0​

Answer 1

b

Explanation:

2x - y = 5

y = 2x - 5 ..... y = mx + b m: slope = 2 b: y intercept = -5

2x - y =0

y = 2x y = 2x + 0 ..... slope=2 y intercept=0 (0,0) origin
