2. Consider the following graph and rotate point P 90° counterclockwise
around two points: the origin and (-2,4). Sketch both points on the
graph.

Step-by-step explanation:

Given

Required

Rotate 90 degrees counterclockwise

Show both points on graph

When a point is rotated counterclockwise by 90 degrees, the new point is:

In

Hence:

See attachment for graph

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

the answer is b
