alleryHow many solutions does a single linear equation in two variables, like y = x + 22, have?
AExactly one
BInfinitely many
CExactly two
DNo solution
Answer & Solution
Correct answer: B. Infinitely many
1. Each value chosen for x gives a matching value of y.
2. There are endless values for x, so there are endless solutions.
3. One equation alone cannot fix both unknowns.
