What’s the square root of -121

Mathematics
1 answer:
irakobra [83]3 years ago
5 0
The answer is 11 i

<em />
<em>Explanation:
</em>
The square root needs to be a number that can be multiplied by itself and equal the original number.

In this case, the number is 11, 11*11 = 121

However, you are looking for the square root of a negative number, due to this you would add i to the answer,
i = imaginary number, or -

( Depending on your grade/ teacher however, you can put "no solution"

Find the slope passing through the points (-3,4) and (2,-1).
stellarik [79]
1)

Given two points: (x₁,y₁) and (x₂,y₂) the slope of the line passing through these points would be: 
m=(y₂-y₁)/(x₂-x₁)

Data:
We have two points, (-3,4) and (2,-1), therefore, the slope of the line passing through these points will be: 

m=(-1-4) /(2+3)=-5/5=-1

Answer: The slope would be -1. 

2)
slope-intercept form of a line:
y=mx+b
m=slope
b=y-intercept

Therefore:
m=2
b=y-intercept=-4

The line would be: y=2x-4

answer: the equation of this line would be: y=2x-4
