What is the slope of the line that passes through the points (5,10) and (11,-12)

-11/3

Step-by-step explanation:

We have two points so we can find the slope using the slope formula

m = ( y2-y1)/(x2-x1)

   = ( -12-10)/(11 -5)

   = -22/6

    = -11/3

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.

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
