(0, 0 )

ax + by + c = 0, will represent equation of straight line parallel y-axis if:

Choose an answer

a = 0

b = 0

c = 0

a = 0, c = 0

General form of equation of line is:

Choose an answer

ax - by + c = 0

ax + by - c = 0

ax + by + c = 0

ax - by - c = 0

undefined

Choose an answer

ax + by + c = 0 has matrix from as:

Choose an answer

|ax + by| = |-c|

[ax + by ] = [c]
