Question

fill in the blank in the sentence below so that the resulting statement is true. the equation y = 3 is line.

Explanation:

Step1: Recall line - types in coordinate - plane

In the coordinate - plane, the equation of a horizontal line is of the form $y = k$, where $k$ is a constant.

Step2: Analyze the given equation

The equation $y = 3$ has $y$ equal to a constant value ($3$) for all values of $x$. This means that for any $x$ - value, the $y$ - value is always $3$.

Answer:

a horizontal
