The equation you provided, \( y = -2x = 3 \), seems to have a formatting issue. It looks like you're combining two equations.
If you meant \( y = -2x \) and want to find when it equals 3, you can set up the equation:
\[ -2x = 3 \]
To solve for \( x \):
- Divide both sides by -2:
\[ x = -\frac{3}{2} \]
Now, you can find \( y \) using \( y = -2x \):
\[ y = -2\left(-\frac{3}{2}\right) = 3 \]
So the point of intersection is \( ( -\frac{3}{2}, 3 ) \).
This means there is exactly one solution to the equation you intended to express, which intersects at the point mentioned above. If you have a different interpretation or a specific equation in mind, please clarify!
