Answer:
Coordinates switch, and the new y-coordinate changes sign
Explanation:
We have point A with the coordinates (-1,2), when we rotate it c90º it becomes (2,1).
What happened? The coordinates switched and the x-coordinate of A (-1) became the y-coordinate of A' (1) and it changed its sign.
Answer: y= -3/2 -5
explanation:
The slope is 3/-2, and it slopes down. making it a negative slope/fraction
And the point is on -5 on the Y axis.
Making the answer y= -3/2-5
