Answer:
(2,1)
Step by step explanation:
Please find the attachment.
We have been given that line
is horizontal and passes through point (1,1). Line
is vertical and passes through point (2,2). We are asked to find point of intersection of line
and line
.
Line
is a horizontal line so y-coordinate will be 1 for any value of x. Line
is a vertical line, so x-coordinate will be 2 for any value of y.
Therefore, intersection point of both lines will include x-coordinate of line
and y-coordinate of line
that is (2,1).
Answer:

Step-by-step explanation:
Given

Rotation = +270 degrees
Required
Determine the new coordinates of Q (i.e. Q')
When a point (x,y) is rotated +270° about the origin, the new coordinates is: (y,−x)
So:

Where:
and 
Q' will be:
