please help, solve the following graphically. Show work on axes given, include proper labels (i. e label lines with equations and label points of intersection) and write your solution using interval notation

Write a function for a rotation 90 degrees counter clockwise about the origin, point 0

Hi, can anyone show me how to do this problem? 100 points for this. in advance
