Is this graph a function or not a function?

It is a function.

Step-by-step explanation:

You can test if a graph is a function if you draw a vertical line anywhere on the graph and you see it hits two points.

This is the table for the graph.

Remember these rules:

Each x value, or input, has its unique y value, or outputIf you draw a vertical line anywhere on the graph, it should only go through one point

We can check these two rules for this graph:

Does each x value have its own, unique y value? YesIf you draw a vertical line anywhere on the graph, does it only go through one point? Yes, there are no overlaps

Keep in mind that two different x-values can have the same y value.

Figure 1:

It has two x values with the same y-values.

Figure 2 and 3:

The vertical line goes through two points. So the same x-value has two different y-values.

6x + y = -38 is the standard form of equation

Solution:

Given that,

y = -6x - 38

We have to write the equation in standard form using integers

The standard form of equation is given as:

Ax + By = C

Where,

x and y are variables and A, B, and C are integers

From given equation,

y = -6x - 38

Shift the variable terms to the left side of the equation and constants to right side of equation

6x + y = -38

Thus the standard form of equation is found
