For the linear function y = 2x + 1, what is y when x = -3?

Explanation:
When evaluating a linear function at a given x, you substitute that x into the expression and simplify. For y = 2x + 1, plug in x = -3: y = 2(-3) + 1. Multiply to get -6, then add 1 to get -5. So the y-value is -5, the only output for that input. The other numbers come from common slips, like forgetting the +1 or mishandling the arithmetic, but the correct substitution gives -5.
