Based on the graph which models the function at x = -2 (see attachment), the corresponding y-value is y = 3.

What is a function?

In Mathematics, a function can be defined as a mathematical expression which can be used to define and show the relationship that exist between two or more variables in a data set.

In this scenario, there are several values (points) on the given linear graph expressed as a coordinate (x, y). Hence, the x-values on the x-axis is directly proportional to the y-values on the x-axis.

By critically observing the graph which models the function at x = -2 (see attachment), we can logically deduce that the corresponding y-value is three (3).

Answer:

The slope is -4

Step-by-step explanation:

To find the slope in this equation you first need to find the difference of y.

2 + (-4) = -2

-2 + (-4) = -6

so the difference of y is -4

Then you find the difference of x

0 + 1 = 1

1 + 1 = 2

So, the difference of x is 1

slope is rise over run (rise meaning the y-axis and run meaning the x-axis)

so the slope is -4/1

Solve the triangle.B = 73°, b = 15, c = 8
Select one:
a. C = 35.9°, A = 71.3°, a ≈ 15.2
b. C = 30.7°, A = 76.3°, a ≈ 15.2
c. C = 30.7°, A = 76.3°, a ≈ 21.3
d. Cannot be solved

Answers

Using the sine law of triangles to solve for angle C:

b / sin B = c / sin C

C = arcsin (c * sin B / b)
C = 30.7°

Since interior angles of a triangle always add up to 180°, we can use this to solve for angle A:

angle A = 180° - 73° - 30.7°
angle A = 76.3°

Having solved for angle A, we can solve for side a using the sine law.

a / sin A = b / sin B

a = b * sin A / sin B
a = 15.2

Therefore, the correct answer is B.

HELPPPPP!!!!!!!! ASAPPPPPPP!!!!!!!!!!Choose the best explanation for why the graph shown is a line of best fit.

The graph shows a line of best fit because the points fit around the line.

The graph shows a line of best fit because there is a straight line.

The graph shows a line of best fit because the association is zero.

The graph shows a line of best fit because the points are plotted evenly above and below the line.

Answers

The best explanation is that the graph shows a line of best fit because the points are plotted evenly above and below the line option (D) is correct.

What is the line of best fit?

A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.

$\rm m = (n\sum xy-\sum x \sum y)/(n\sum x^2 - (\sum x)^2) \n\n\n\nrm c = (\sum y -m \sum x)/(n)$

We have a line of best fit shown in the picture.

As we know if the slope of the line is positive then the correlation will be positive.

From the line of best fit:

Because the points are evenly spaced above and below the line, the graph displays a line of best fit.

Thus, the best explanation is that the graph shows a line of best fit because the points are plotted evenly above and below the line option (D) is correct.
