Question

1. graph and label the following lines on the graph.

line a y = 5
line b y = - 3
line c y = 1

Explanation:

Step1: Recall line - graphing rule

For a line of the form $y = k$ (where $k$ is a constant), it is a horizontal line passing through the point $(0,k)$ on the $y$-axis.

Step2: Graph Line A

For $y = 5$, draw a horizontal line passing through the point $(0,5)$ on the $y$-axis and label it as Line A.

Step3: Graph Line B

For $y=-3$, draw a horizontal line passing through the point $(0, - 3)$ on the $y$-axis and label it as Line B.

Step4: Graph Line C

For $y = 1$, draw a horizontal line passing through the point $(0,1)$ on the $y$-axis and label it as Line C.

Answer:

Graph a horizontal line through $(0,5)$ and label it Line A, a horizontal line through $(0,-3)$ and label it Line B, and a horizontal line through $(0,1)$ and label it Line C on the given graph.
