Original practice question

Solve the system of equations $y = -1x^2 + 2x + -1$ and $y = -2x + -1$.

Worked explanation

• Eliminate one variable

  \[\text{Solutions: } (0, -1), \quad (4, -9)\]

• Write ordered pairs

  \[(0, -1), \quad (4, -9)\]

\[(0, -1), \quad (4, -9)\]

Original VectorPaths practice; not an official VCAA question or marking rubric.
