Question

. A straight line passes through the point (-1,2) and its distance from the origin is

one unit. Find its equation.

Answer 1

y = -1/2x + 3/2

Explanation:

(2-0)/(-1-0) = -1/2

2 = -1/2(-1) + b

2 = 1/2 + b

b = 3/2

Answer 2

Answer: y = -1

Explanation:

Assuming "distance from the origin is one unit" means distance on the x axis, a vertical straight line having an x-intercept of -1 would satisfy thede requirements. y = -1 isn't much of an equation, but it goes through (-1,2) and is 1 unit (-1) from the origin.
