**Answer: a. The rise is –5, the run is 4.**

**Step-by-step explanation:**

Given :- A line in the Cartesian plane passes through the points (–2, 4) and (2, –1)

Let and

We know that **rise of a line = vertical change of points=change in the coordinates of y**

=

**Run of line=horizontal change of points=change in the coordinates of x**

=

Therefore, The rise is –5, the run is 4.

the formula on how u calculate the simple interest is P×PRT ( PRICE *RATE *TIME )

THE THING IS WHTS THE RATE IN HERE????

**Answer:**

This mapping isn't a function.

**Step-by-step explanation:**

A **mapping** specifies a relation between two sets of items (input and output). For example, a mapping of the form would map the input to output and map the input to output .

A **function** is a mapping where each input is associated with exactly one output.

Note that both and are in the mapping given in this question. The input is mapped to more than one outputs. Thus, this mapping isn't a function.

**Answer:**

The first one is F' each one is around $36
