To determine the counter clockwise rotation of 180 degree about the origin
When rotating a point 180 degrees counterclockwise about the origin our point H(x,y) becomes H'(-x,-y).
From the rotation formula about the origin counterclockwise 180 degree is
Therefore the correct answer is Option A
Answer:
Each term in pattern Y is 3 times the corresponding term in pattern X.
Step-by-step explanation:
Given the information:
X - 0, 5, 10, 15, 20
Y - 0, 15, 30, 45, 60
We can use deduce from physical observation of the data that each term in pattern Y is 3 times the corresponding term in pattern X.
However, to establish our relationship, we can plot the linear relationship and generate the equation of the line.
Thus gives us :
Y = 3X + 0
Which means for every pattern in Y, it is 3 times the corresponding pattern in X
