45. Linearity of an Explicit Affine Map

Over R, the 2×2 matrix is M=[[7, 4], [-2, 20]]. In the fixed standard basis, T:R²→R² is T(x)=Mx, with column vectors. The affine map F(x)=Mx+b has b=[-19, 0]. Is F linear on the whole R²?

View answer and explanation

No

Here F(0)=b=[-19, 0]. For this explicitly specified affine form, linearity holds exactly when b=0, giving No. No invertibility condition on M is required; this is not merely a test at a pair of nonzero inputs.
