Answer:
Option (3)
Step-by-step explanation:
There are two inequalities graphed in the figure attached.
1). Solid line having shaded above the solid line (passing through origin) will be represented by the equation,
2). Another dotted line having shaded area below the line will be represented by the inequality,
Common shaded area of these inequalities will be the solution area.
All the ordered pairs lying in this area will be the answer.
In the given options,
Ordered pairs given in Option (3) lie in the common shaded area.
By using the linear function which models the data in the given table, if x = 2, then y is approximately: A. -11.
<h3>What is a scatter plot?</h3>A scatter plot can be defined as a type of graph which is used for the graphical representation of the values of two variables, with the resulting points showing any association (correlation) between the data set.
<h3>What is a linear function?</h3>A linear function can be defined as a type of function whose equation is graphically represented by a straight line on the cartesian coordinate.
By critically observing the graph (see attachment) which models the data in the given table, we can infer and logically deduce that the linear function is given by:
y = -5.9245x + 0.9958
If x = 2, then y is approximately:
y = -5.9245(2) + 0.9958
y = -11.849 + 0.9958
y = -10.8532 ≈ -11.

The type of numbers, rational and irrational from the numbers Keisha writes are;
a. Rational numbers; -9, 3.0, 2, and 2.42
b. Irrational numbers; √8
<h3>What is the difference between rational and irrational numbers?</h3>Rational numbers are numbers are numbers that can be expressed as a ratio of two whole numbers P/Q, in which, <em>Q </em>≠ 0
Irrational numbers are those that cannot be expressed as a fraction P/Q
The given numbers are;
-9, √8, 3.0, 2, 2.42
- -9 = -9/1
- √8 = 2•√2 (√2 cannot be expressed as a fraction of two whole numbers)
- 3.0 = 3/1
- 2 = 2/1
a. The rational numbers are therefore;
- -9, 3.0, 2, and 2.42
b. The irrational number is; √8
