Answer:
neither a or b
Step-by-step explanation:
a function has to have each X have a Y
a domain is paired with exactly one range value.
it has to pass the vertical line test
independent variable is X
dependant variable is Y
student name = x
colors/teachers is Y
so since there is the chance the students can have the same teacher and/or favorite color. then it is not a function

According to the statement of the question, we conclude that the area of a square is requested, whose value is 171 in²
The area of a square is given by the expression:
A = S²
<em>where S is the side of the square - just what we want to know</em>
So:
A = S²
171 = S²
√171 = S
<h3>S ≈ 13.08in</h3>
Answer:

For perpendicular lines, m1m2 = -1 or m2 = -1/m1; where m1 and m2 are the slopes of the lines.
Here line 1 is 3x - 7y = 42
7y = 3x - 42
y = 3/7 x - 6; Hence m1 = 3/7
m2 = -1/(3/7) = -7/3
Required equation y - y1 = m2(x - x1)
y - (-8) = -7/3(x - (-3))
y + 8 = -7/3(x + 3)
y + 8 = -7/3 x - 7
y = -7/3 x - 7 - 8
y = -7/3 x - 15
