STEP 1

Assumptions1. Shelly completed $x$ tasks and scored90 points on each one.
. Terrence's total points in the game are represented by the expression $90x -20$.

STEP 2

The expression for Terrence's total points is a linear expression in the form $ax + b$, where $a$ is the coefficient of $x$ and $b$ is the constant term.

STEP 3

In the given expression, $90x -20$, $90$ is the coefficient of $x$ and $-20$ is the constant term.

STEP 4

The coefficient of $x$ (90) represents the number of points Terrence earns per task, which is the same as Shelly.

STEP 5

The constant term in this expression, $-20$, represents a fixed amount of points that is independent of the number of tasks completed.

In the context of this problem, the constant term $-20$ could represent a penalty or deduction of20 points that Terrence received, which is subtracted from his total points.
Therefore, the constant term of the expression represents a deduction of20 points from Terrence's total score.
