If the 3 points are collinear, then the slopes of all line segments connecting the points are the same.
Thus,
-6 - (-8) 2
m = ------------- = -------- = -1/2
-7 - (-3) -4
Then the following must be true:
4-(-6) 10
-1/2 = ------------ = ---------
c - (-7) c + 7
Cross multiplying, -(c+7) = 20, and c+7 = -20, so that c = -27

Answer:</h3>
C. No, the graph fails the vertical line test
<h3>
Step-by-step explanation:</h3>
Functions describe the relationship between the dependent variable, y, and the independent variable, x.
Functions
For a graph to be a function, x-values cannot repeat. This means that one x-value cannot have more than one y-value.
However, functions can have repeating y-values. So, y-values can have more than one x-value; as seen in quadratic functions. This means that answer B cannot be correct.
Vertical Line Test
The vertical line test is a way to determine if a graph is a function. A graph passes the vertical line test if you can draw a vertical line at every point on the coordinate plane and not have it intersect with the graph more than once.
On the graph in the question, a vertical line would intersect with the graph twice at the x-values greater than -1. Since the graph fails the vertical line test, it is not a function.
We will assume that the number is n
one eighth of the number = 1/8 x n = n/8
we know that this result n/8) is less than or equal (<=) 3
therefore, the inequality is:
n/8 <= 3
To find the area of a rectangle, simply multiply the length by the width.
2/5 * 1/3 = 2/15
So, the area is 2/15.
