That represents exponential growth because we are multiplying by 2.1 every time. Since you are multiplying by a number greater than 1 that means that the number is getting bigger as x gets bigger. This means that we have exponential growth.
Answer:
The image if the point is (-7, -9)
Step-by-step explanation:
- If The point (x, y) rotated about the origin by angle 90° counterclockwise, then its image is (-y, x)
- If the point (x, y) rotated about the origin by angle 180° counterclockwise, then its image is (-x, -y)
- If the point (x, y) rotated about the origin by angle 270° counterclockwise, then its image is (y, -x)
∵ The given point is (9, -7)
∴ x = 9 and y = -7
∵ The given point is rotated 270° counterclockwise about the origin
→ By using the third rule above
∴ The image of the point is (y, -x)
→ That mean change the sign of x-coordinate, then switch them
∵ x = 9 and y = -7
∴ The image if the point is (-7, -9)
