Answer:
Part a) The rule of the translation is (x,y) -----> (x+1,y+3)
Part b) The coordinates of the drummer's final position are (-1,-2)
Step-by-step explanation:
Part a) Write a rule to describe the translation
we know that
The lead drummer moved 3 steps up and 1 step right.
so
3 steps up ----> that means (y+3)
1 step right ---> that means (x+1)
The rule of the translation is equal to
(x,y) -----> (x+1,y+3)
Part b) What were the coordinates of the drummer's final position?
we know that
The drummer's initial position is the point (-2,-5)
Applying the rule of the translation
(x,y) -----> (x+1,y+3)
(-2,-5) -----> (-2+1,-5+3)
(-2,-5) -----> (-1,-2)
therefore
The coordinates of the drummer's final position are (-1,-2)
Answer:
The other point on the diameter which is also on the circle is; (-3, 2)
Step-by-step explanation:
The center of the circle, also a point where the diameter crosses, is (3, 6)
The diameter touches the circle at point (9, 10)
The displacement is (9 - 3, 10 - 6) = (6, 4)
This means that we move, +6 units along the x-axis and +4 units along the y-axis , from the center of the circle in order to reach point (9, 10)
If we want to reach the other point on the diameter which also on the circle, we move -6 units along the x-axis and -4 units along the y-axis to get;
(3, 6) - (6, 4) = (-3, 2)
