Given the graph of a system of equations, Tyrone estimated the solution to be (–2.1, –3.2). Analyze Tyrone’s estimated solution. Is he correct? If not, what was his mistake?

• Yes, Tyrone is correct.

• No, he did not use the intersection point.

• No, the x-coordinate is closer to -3 than -2.

• No, he switched the x- and y-coordinate values.
