sqrt(11) ≈ 3.31662479…, so −sqrt(11) ≈ −3.3166…; to the nearest tenth that is −3.3.

Because −3.3 lies between −4 and −3 and is closer to −3 than to −4, place the point at the −3 tick mark.

Explanation: sqrt(11) is irrational, so its exact decimal expansion isn’t finite; a decimal estimate (like −3.3) gives a convenient, measurable position on the number line, making it easier to plot accurately.
