A point (a, b) in the second Quadrant, is any point where a is negative and b is positive.
For example (-3, 5), (-189, 14) etc are all points in the 2.Quadrant
Rotating a point P(x, y) in the second Quadrant 180° counterclockwise, means rotating 180° counterclockwise about the origin, which maps point P to P'(-a, -b) in the fourth Quadrant.
Answer:
x = 2
Step-by-step explanation:
5x - 2 = 8
5x = 8 + 2
5x = 10
x = 10/5
x = 2
slope intercept form equation, y = mx + b
answer, y = -2x + 4
