The average rate of change from 1960 to 2000 was $2.90
Well, the y axis is the one that goes up and down, so it's pretty clear that it's flipped over that. After it gets reflected over the y axis, the -2 changes into 2 (so -2 is multiplied by -1) as it is the x coordinate, making the center (2,5). After that, you'd want to get the y value down by 4 to match it up with (2,1), meaning that the second option down is right!
Hello,
Answer B
Just see the graphs. y=x² is passing by (0,0)
I'm going to write out the work and take a pic. hope this helps you understand if not, feel free to ask me Q's! :)

thursday 138 (46 x 63 / 21 = 138)
friday 99 (33 x 63 / 21 = 99)
