Two separate linear functions are expressed by the graph and by the equation. select all that apply.
the slope is negative for both functions.
the equation has a steeper slope than the line in the graph.
the slope of the line in the graph is -2.
the graph and the equation express an equivalent function.

First option: The slope is negative for both functions.

Fourth option: The graph and the equation expressed are equivalent functions.

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

Where "m" is the slope and "b" is the y-intercept.

Given the equation:

We can identify that:

Notice that the slope is negative.

 We can observe in the graph that y-intercept of the other linear function is:

Then, we can substitute this y-intercept and the coordinates of a point on that line, into and solve for "m".

Choosing the point , we get:

Notice that the slope is negative.

Therefore, since the lines have the same slope and the same y-intercept, we can conclude that they are equivalent.
