What’s the equation for this
LekaFEV [45]
<h2>Answer:</h2>

Hope it work for u

<h2>Step-by-step explanation:</h2>

We can make points from the given figure as ,

1 point =(x1, y1)=(-2, -3)

2nd point =(x2, y2)=  (0, -6)

3rd point = (x3, y3)=(2 , -9)

Now the equation of line is,

<h2>Y=m X+ c  where   m is slope and c is constant </h2>

now two point formula of slope is ,

<h2>m = y2-y1/x2-x1</h2>

putting points in it we get

m=(-6-(-3))/(0-(-2)

m=-3/2 is slope

Now to find C putt the value of m and 3rd point in equation of line we get

y3=m(x3)+c

-9=(-3/2)(2)  +c

C= -9+3

C=-6  is value of c

Now at last putt the value of C and m in equation of line we get the required equation ,

<h2><u>Y=(-3/2)X-6  </u> Ans</h2>

What is the assessed valuation of a house with a $67,170 market value and a 49 percent assessment rate?
-BARSIC- [3]
Had to look for the missing options and here is my answer.

Given that the market value of the house is $67,170 and it has a 49 percent assessment rate, the assessed valuation of this house would be $32,913. So how we got this amount is that we multiplied 0.49 by 67,170 and we got 32,913.3. Hope this answers your question.
