The answer is gonna be -3/14
The graph illustrates a linear function, because the graph is a straight line
The equation of the graph is <em>(d) y = x +3</em>
The points on the line are:


First, we calculate the slope (m)

Substitute values for x1, x2, y1 and y2

Simplify

Divide

The equation of the line is then calculated using the following formula:

Substitute values for m, x1 and y1

Simplify

Open bracket

Hence, the equation of the graph is <em>(d) y = x +3</em>

Answer is C or 5/6
Explanation: use calculator
Answer:
vertical line
Step-by-step explanation:
If it is possible to draw any vertical line (a line of constant x) which crosses the graph of the relation more than once, then the relation is not a function.
Answer:
Graph U
Step-by-step explanation:
A graph is used to illustrate the relationship between variables.
For graph U:
Graph U is positive on (-∞, ∞). The graph also increases on (-∞, ∞). The graph approaches 0 as x approaches -∞.
For graph V:
Graph V is positive on (-∞, ∞). The graph also increases on (-∞, ∞). The graph is negative as x approaches -∞.
For graph W:
Graph W is positive on (-∞, 0). The graph also increases on (-∞, 0). The graph approaches 0 as x approaches -∞.
For graph X:
Graph X is positive on (-∞, ∞). The graph also increases on (-∞, ∞). The graph is negative as x approaches -∞
For graph Y:
Graph Y is positive on (-∞, ∞). The graph also decreases on (-∞, ∞). The graph approaches 0 as x approaches ∞.
For graph Z:
Graph Z is negative on (-∞, ∞). The graph also decreases on (-∞, ∞). The graph is approaches 0 as x approaches -∞
