x: —5, —2 ,—1, 1
y: 4, 1, —2, —4
Can the function be represented by a straight line? Why/Why not?
A. No;the slope of the segment between U and W and the slope of the segment between T and V are both are negative.
B. No;the slope of the segment between U and V is not equal to the slope of the segment between T and V.
C. Yes;the slope of the segment between T and U is equal to the slope of the segment between V and W.

Answer 1
