You have the correct answer. Nice work. If you need to see the steps, then see below

-------------------------------------------------------------------------------

First we need to find the midpoint of H and I
The x coordinates of the two points are -4 and 2. They add to -4+2 = -2 and then cut that in half to get -1

Do the same for the y coordinates: 2+4 = 6 which cuts in half to get 3

So the midpoint of H and I is (-1,3). The perpendicular bisector will go through this midpoint

---------------------

Now we must find the slope of segment HI

H = (-4,2) = (x1,y1)
I = (2,4) = (x2,y2)
m = (y2 - y1)/(x2 - x1)
m = (4 - 2)/(2 - (-4))
m = (4 - 2)/(2 + 4)
m = 2/6
m = 1/3
Flip the fraction to get 1/3 ---> 3/1 = 3
Then flip the sign: +3 ----> -3

So the slope of the perpendicular bisector is -3

-----------------------

Use m = -3 which is the slope we found
and (x,y) = (-1,3), which is the midpoint found earlier
to get the following
y = mx+b
3 = -3*(-1)+b
3 = 3+b
3-3 = 3+b-3
0 = b
b = 0

So if m = -3 and b = 0, then y = mx+b turns into y = -3x+0 and it simplifies to y = -3x

So that confirms you have the right answer. I've also used GeoGebra to help confirm the answer (see attached)

How long would it take to have $1335.60 in interest if principal is $5300 and interest rate is 7%
Solnce55 [7]
(5300 + 1335.6)  = 5300(1 + 0.07)^n   where n is the number of years required

6635.6 = 5300(1.07)^n
(1.07)^n = 1.252
n log 1.07  = log 1.252

n =  log 1.252 / log 1.07 = 3.32 years Answer

The income of a person is Rs 18,000 per month .due to the exemption of the income of Rs 1,40,000 per year, he has paid Rs 11,400
svp [43]

If the income of a person is Rs 18,000 per month , the exemption of the income is Rs 1,40,000 per year, If he has paid Rs 11,400 as an income tax at the end of the year . The percent per annum of the tax paid is: 15%.

<h3>
</h3><h3>Tax percentage</h3>

Given:

Income of a person=Rs 18,000 per month

Exemption income per year=140,000

Income tax paid=11,400

First step is to the calculate the Income per year since the  income of a person is Rs 18,000 per month

Income per year= 18,000 ×12

Income per year=216,000

Second step is to calculate the taxable income

Taxable income=216,000-140,000

Taxable income=76,000

Third step is to calculate  the tax Percentage per annum

Tax percentage=11,400/76,000×100

Tax percentage=15%

Therefore If  he has paid Rs 11,400 as an income tax at the end of the year . The percent per annum of the tax paid is: 15%.
