Dashna paid a $20 fee for a booth at an art fair so she could sell her ceramic bowls. She will earn $10 for every ceramic bowl s
he sells. The equation y = 10x – 20 represents the amount of money, y, that Dashna will earn selling x ceramic bowls at the art fair. Which graph represents the amount of money Dashna could earn at the art fair?

Answer:
(2,3)
Step-by-step explanation:
We are given that triangle PQR lies in the xy-plane, and coordinates of Q are (2,-3).
Triangle PQR is rotated 180 degrees clockwise about the origin and then reflected across the y-axis to produce triangle P'Q'R',
We have to find the coordinates of Q'.
The coordinates of Q(2,-3).
180 degree clockwise rotation about the origin then transformation rule
The coordinates (2,-3) change into (-2,3) after 180 degree clockwise rotation about origin.
Reflect across y- axis the transformation rule
Therefore, when reflect across y- axis then the coordinates (-2,3) change into (2,3).
Hence, the coordinates of Q(2,3).
