Answer:
B. -1
Step-by-step explanation:
The relevant points on the graph are (1, 3) and (4, 0). The average rate of change can be found using the slope formula ...
m = (y2 -y1)/(x2 -x1)
m = (0 -3)/(4 -1) = -3/3 = -1
The average rate of change from x = 1 to x = 4 is -1.

Answer:
- As the slopes of both lines 'm' and 'n' are the same.
Therefore, we conclude that the equation x-2y=4 represents the equation of the line 'n' if lines m and n are parallel to each other.
Step-by-step explanation:
We know that the slope-intercept of line equation is

Where m is the slope and b is the y-intercept
Given the equation of the line m
y = 1/2x - 4
comparing with the slope-intercept form of the line equation
y = mx + b
Therefore,
The slope of line 'm' will be = 1/2
We know that parallel lines have the 'same slopes, thus the slope of the line 'n' must be also the same i.e. 1/2
Checking the equation of the line 'n'

solving for y to writing the equation in the slope-intercept form and determining the slope

Add -x to both sides.


Divide both sides by -2


comparing ith the slope-intercept form of the line equation
Thus, the slope of the line 'n' will be: 1/2
- As the slopes of both lines 'm' and 'n' are the same.
Therefore, we conclude that the equation x-2y=4 represents the equation of the line 'n' if lines m and n are parallel to each other.
The slope of the line is 
First, you must find 2 points.
(-6,8) (-2,5)
Then, you must substitute the value of the points in.

Finally, simplify the fraction.
