Question

or the graphs below:

1. let b = 1

vertex: ________ h: __ k: ____
point: ________ x: __ y: ____

Explanation:

1. Identify the vertex of the V-shaped graph: this is the lowest point where the two lines meet.
2. Extract the coordinates of the vertex as $(h,k)$.
3. Select any other clear point on the graph to get $(x,y)$.

Answer:

Vertex: $(-2, 0)$
h: $-2$
k: $0$
Point: $(1, 3)$
x: $1$
y: $3$

(Note: Other valid points on the graph include $(-4, 2)$, $(0, 2)$, etc.)
