Question

inequalities and solutions

1. the temperature in city a is 2°c. let a represent the temperature in city a in degrees celsius. write the equation that represents the temperature in city a. then graph the solution to the equation on the number line.

Explanation:

Step1: Define the variable and equation

Let \( a \) represent the temperature in city A (in \( ^\circ \text{C} \)). The temperature is given as \( 2^\circ \text{C} \), so the equation is \( a = 2 \).

Step2: Graph the solution on the number line

To graph \( a = 2 \) on the number line, we find the point corresponding to \( 2 \) (between \( 1 \) and \( 3 \)) and mark it with a closed dot (since the solution is a single point, \( a = 2 \), not an inequality with a range).

Answer:

The equation is \( \boldsymbol{a = 2} \). To graph it, place a closed dot at \( 2 \) on the number line.
