What are the coordinates of the image of point (−1, 5) after a counterclockwise rotation of 90º about the origin?

Step-by-step explanation:

We have been given the coordinates of a point and we are asked to find the coordinates of he point after a counterclockwise rotation of 90º about the origin.  

We know that after rotating a point 90 degree counter-clockwise about the origin, the x and y-coordinates changes places with each other and x-coordinate of new point becomes the negative of y-coordinate.

Applying the rotation rule the coordinates of new point would be:

Therefore, the required coordinates of the given point after a counterclockwise rotation of 90º about the origin would be .

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.

answer: 5100 just subtract
