Question

Which of the following correctly represents when b = 0 in the standard equation ax + by + c = 0

• A. ax + c = 0
• B. by + c = 0
• C. ax + by + c = 0
• D. None of the above

Answer 1

The correct option is A ax + c = 0

The standard equation ax + by + c = 0
Now, when b = 0,
ax + 0. y + c = 0
ax + 0 + c = 0
ax + c = 0
Thus, ax + c = 0 represents the standard equation correctly when b = 0
