Answer: 5
Step-by-step explanation:
Range = highest value - lowest value
The highest value from the data set given = 1
The lowest value = -4
Therefore :
Range = 1 - (-4)
Range = 1 + 4
Range = 5

Answer:
The answer is
<h2>y = - 2x + 1</h2>
Step-by-step explanation:
Equation of a line is y = mx + c
where 
m is the slope 
c is the y intercept
To find the equation of the parallel line we must first find the slope of the original line 
From the question the original line is
y = - 2x + 7
Comparing with the general equation above
Slope = - 2
Since the lines are parallel their slope are also the same
Slope of parallel line = - 2
The equation of the line using point (-1, 3) and slope - 2 is

We have the final answer as
