Option 2
Martha estimated the quotient. Martha error was she should have rounded -8.02 to -8.
<u>SOLUTION:
</u>
Given that, Martha estimated the quotient of -71.81 and -8.02 using rounding to the nearest whole number.
And she committed an mistake. We have to find the error made by Martha while calculating quotient.
She treated -71.81 to be 72 and -8.02 to be 9. As both the number are negative there will be no problem when we get quotient.
When treated as above she got quotient as 8.
But in general, the quotient is not 8.
If we see options, we derive an conclusion.
<u>Option (1) </u>
she should have rounded 71.81 to 70, no this is not correct as 72 is nearest whole number.
<u>Option (2)</u>
she should have rounded 8.02 to 8, yes this is correct conclusion.
<u>Option (3)</u>
she should have divided 8 by 72, no this is not correct, we should divided 72 by 8.
<u>Option (4) </u>
she didn’t make an error, this is wrong as in 2nd option we caught an error.
Hence, second option is correct.
It shouldn't be too tough to find one of those, seeing that there are
an infinite number of them.
To create one, take any integer, positive or negative, and multiply it by itself.

Answer:
Step-by-step explanation:
Perpendicular equations have OPPOCITE MULTIPLICATIVE INVERCE <em>RATE OF</em><em> </em><em>CHANGES</em><em> </em>[<em>SLOPES</em>], so 1⅕ becomes −⅚, and we move forward with plugging the information into the Slope-Intercept formula:
![\displaystyle -8 = -\frac{5}{6}[24] + b \hookrightarrow -8 = -20 + b; 12 = b \\ \\ \boxed{y = -\frac{5}{6}x + 12}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20-8%20%3D%20-%5Cfrac%7B5%7D%7B6%7D%5B24%5D%20%2B%20b%20%5Chookrightarrow%20-8%20%3D%20-20%20%2B%20b%3B%2012%20%3D%20b%20%5C%5C%20%5C%5C%20%5Cboxed%7By%20%3D%20-%5Cfrac%7B5%7D%7B6%7Dx%20%2B%2012%7D)
To write this in Linear Standard Form, perfourm he following:
y = −⅚x + 12
+ ⅚x + ⅚x
___________
⅚x + y = 12 [We cannot leave the equation this way, so multiply the equation by the denominatour to eradicate the fraction.]
6[⅚x + y = 12]
