Y = -1/2x -1
hope this helped
X = -1
Y=1
This should be the answer
Answer: observational study
Step-by-step explanation:
Observational study : A study in which an observer analyse one or more characteristics of a population (depends on the objective of the study) by just observing the individuals in a sample of the population, but he / she never influence the variables of interest.
Design experiment : In this experimenter design an experiment with a series of tests to check the change in the dependent variable. Here , the experimenter influences the variables of interest.

here , the poll is just observing the interest of students instead of influencing them.
Hence, the study depicts an observational study.
Answer:
Option A is correct.
Point T is not co-planar with points A, C and D
Step-by-step explanation:
Co-planar states that those which lies in the same plane.
Point A, C and D are lies in the Plane AEDC.
Since, this plane also contains points S and U.
Thus, point A, C , D , E, S and U are co-planar
but point T does not lie in the plane AEDC.
Therefore, point T is not co-planar with points A, C and D
Step-by-step explanation:
the answer is
the Value of b to 2
