Question

graph the line y = 3.

Explanation:

Step1: Analyze the equation

The equation $y = 3$ means for any value of $x$, $y$ is always 3.

Step2: Find points

We can choose some $x$ - values, like $x=-2,0,2$. When $x = - 2,y = 3$; when $x = 0,y = 3$; when $x = 2,y = 3$.

Step3: Plot points and draw line

Plot the points $(-2,3),(0,3),(2,3)$ on the coordinate - plane and then draw a straight line passing through these points. The line is parallel to the $x$ - axis and intersects the $y$ - axis at the point $(0,3)$.

Answer:

Draw a horizontal line passing through the point $(0,3)$ on the $y$ - axis.
