Question

Hi people, please any hint with this? i think if l move 270 degrees 1 space to the left l get -90 but... shows it as wrong thanks

Answer 1

you don't move it to the left, you move it up 1- there are no parentheses so it's a vertical shift

Explanation:

a) move point up one- add 1 to y-coordinate

b) flip over x-axis (multiply y by -1)
