Wanda's graph is incorrect because Claudia needs to earn $80 or more and Wanda's graph shows $80 or less.
Find the vertical and horizontal difference between the two given points:
Horizontal is the Y values: 4 - -4 = 4+4 = 8
Vertical is the X values 7 - -1 = 7+1 = 8
Multiply the changes by the ratio:
Now copy the dot on A 2 places to the left and down 2 places and the dot lands on point (5,2)
8 * 1/4 = 2
Y equals a number minus 5 add 77 to the graph of y equals x minus 1 squared minus 2
