What is the y-intercept of a line that has a slope of –3 and passes through point (–5, 4)? –17 –11 7 19

-11

Step-by-step explanation:

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.

a ≈ 172.05
