Answer:
C. 
Step-by-step explanation:
Alan and his classmates found that the line of best fit through the data had the equation 
The slope of this line is 
If a line would intersect this line of best fit at right angles, then the two lines are perpendicular to each other.
The slopes of perpendicular lines are negative reciprocals of each other,
Hence that line must have slope 
Therefore we look for a line whose slope is
from the given options.
That line is the third option

Answer:
One pair of opposite sides are parallel and congruent
Step-by-step explanation:
As you can see, segment HE and GF are both marked as parallel and congruent
I think -6x^2+17x+17 Hope it helps
C.
Solve for x by simplifying both sides of the equation, then isolating the variable.
x = 77, -77
