Sure! Here's a similar type of student's math question without an answer:
"How do I find the matrix B such that the linear transformation S(y): ℝ² → ℝ³ defined by S(y) = y₁w₁ + y₂w₂ can be expressed in the form S(y) = By for the vectors w₁ = ⎡ 4 ⎤, w₂ = ⎣ -1 ⎦? What dimensions should matrix B have?"
