Answer:
The answer to your question is: first option
Step-by-step explanation:
Data
A (2, 5)
B (-2, -3)
Formula
Slope = m (y2 - y1)/(x2 - x1)
Line (y - y1) = m(x - x1)}
Process
m = (- 3 - 5) / (-2 - 2)
m = -8 / -4
m = 2
Substitution in line equation
(y + 3) = 2 (x + 2) Line equation

1. The point (a,b) rotated 90° counterclockwise about
the origin
becomes (-b,a).

Answer:
0
Step-by-step explanation:
if all the points lie on the same line then they have the same slope
