0.75^2 = 0.5625.....sq rt 0.5625 = 0.75
Answer:
the first statement ( I )
Step-by-step explanation:
Answer:
Yes.
Step-by-step explanation:
If the slope between successive points have the same slope then they will form a straight line.
Slope = ( 3.5- -1) / (-2 - -8) = 4.5/6 = 3/4
Slope = (12.5 - 3.5) / (10 - -2) = 9 / 12 = 3/4
Slope = (20-12.5)/(20-10) - 7.5/10 = 3/4 .
So the answer is yes.
