What are the coordinates of (-4,-2) rotating 90° counterclockwise?
1 answer:
Answer:
(2, -4)
Step-by-step explanation:
The rotation of an object <u>turns</u> the object around a <u>fixed point</u> called the center of rotation.
A <u>rotation</u> of 90° counterclockwise means:
A 90° rotation counterclockwise with the origin (0, 0) as the center of rotation.
The rule for a counterclockwise rotation of 90° about the origin is:
(x, y) → (-y, x)
Therefore:
(-4, -2) → (2, -4)

Answer:
400 times Greater
Step-by-step explanation:
8 x 10^4
10^4 = 10000
10000 x 8 = 80000
2 x 10^2
10^2 = 100
2 x 100 = 200
= 400
Step-by-step explanation:
Move it it up 4 and then find your x intercepts.
Find the x intercepts.
<u>Move the 4 over to the right</u>
<u>Divide out the - </u>
<u>Take the square root of each side</u>
Our x intercepts are at (-2,0) (2,0)
