Given:
A straight line goes through (-2,1), (0,0), and (2,-1).
To find:
The slope of the given line.
Solution:
Slope formula
Consider any two points from the given points.
The line goes through (-2,1) and (0,0). So, the slope of the line is
Therefore, the slope of the line is

The missing number in the given data that has a mean of 79 is: 60.
<h3>How to Find the mean of a Data?</h3>
The mean of a data set is simply the average, that is, it is the sum of all data values divided by the number of data values.
Let x represent the missing number in the data. If the mean is 79, we would have the following:
(89 + 74 + 92 + 80 + x)/5 = 79
(335 + x)/5 = 79
335 + x = 5(79)
335 + x = 395
x = 395 - 335
x = 60
Missing number is: 60.

Answer:
y = -1/2c - 8
Step-by-step explanation:
2c - y = 6
2c -6 = y
Slope: 2. Slope of the perpendicular line: -1/2
Point (-4,-6)
y-intercept = -6 - (-1/2)(-4)
b = -6 -2 = -8
