Answer: Coplanar points.
Step-by-step explanation:
0, 2, 4, 6 is because the rule it to add 2
1, 2,4,8 is a geometric sequence since the rule is to mutliply by 2
1,4,8, 13 is neither even though there is a pattern add 3, add 4 add 5 etc.
You can use Google or a calculated but to check it but it's : 6
Answer:
y = 0
Step-by-step explanation:
A parallelogram is a quadrilateral with opposite sides parallel. Then segment CD must be parallel to AB, and CB must be parallel to DA. Two different segments are parallel if they have the same slope.
slope of DA = (yA - yD)/(xA - xD) = (4 - 2)/(1 - (-1)) = 1
slope of CB = (yB - yC)/(xB - xC) = (2 - yC)/(1 - (-1)) = 1
(2 - yC) = 2 * 1
2 - 2 = yC
0 = yC
Note: coordinates of A are (xA, yA), of B are (xB, yB), of C are (xC, yC) and of D are (xD, yD)
