Triangle pqr is rotated 90 degrees counterclockwise about the origin to form the triangle p'q'r' (not shown). then triangle p'q'r' is reflected across the x-axis to form triangle p"q"r" (not shown). what are the signs of the coordinates (x, y) of point p'?

right

step-by-step explanation:

x=30

step-by-step explanation:

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

entering that problem on the tube might get you an answer
