The equation \( y = -2x = 3 \) seems to be written incorrectly. It appears to be mixing two equations. Let's clarify it.
If you mean that \( y = -2x + 3 \), then this is indeed in the \( y = mx + b \) format, where:
- \( m = -2 \)
- \( b = 3 \)
This is a linear equation, and it represents a straight line. A linear equation in two variables has infinitely many solutions because for each value of \( x \), there is a corresponding value of \( y \).
If you intended something different, please clarify!
