The major thing that differentiate microeconomics from macroeconomics is the object of study. Microeconomics refers to the study of economics at individual, group or business level while macroeconomics involves the study of economics on the national scale, that is the study of the economy of a nation. The economics of a nation is the combination of all the individuals, businesses, households, etc in a country.

Completing the square :
- 9y² - x - 18y + 10 = 0
- 9y² - 18y + 9 - 9 - x + 10 = 0
- <u>(3y - 3)² - x + 1 = 0</u>

![\large\boxed{b=\pm\sqrt{77}}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7Bb%3D%5Cpm%5Csqrt%7B77%7D%7D)
Step-by-step explanation:
![b^2=77\iff b=\pm\sqrt{77}\\\\\text{because}\\\\(-\sqrt{77})^2=77\ \text{and} \ (\sqrt{77})^2=77](https://tex.z-dn.net/?f=b%5E2%3D77%5Ciff%20b%3D%5Cpm%5Csqrt%7B77%7D%5C%5C%5C%5C%5Ctext%7Bbecause%7D%5C%5C%5C%5C%28-%5Csqrt%7B77%7D%29%5E2%3D77%5C%20%5Ctext%7Band%7D%20%5C%20%28%5Csqrt%7B77%7D%29%5E2%3D77)
In order to find a slope, there is an equation:
Y2-Y1/X2-X1
X1=2
X2=3
Y1=5
Y2=0
0-5= -5
3-2=1
Since slope is written as Y/X, slope would be-5/1 or simply, -5.
Now, we need to find the y-intercept.
To do this, shift the original equation:
Original equation: y=-5x+b
Shifted equation: b=y+5x
Now, plug in one of the points.
Let's use (2,5)
b=5+5(2)
5*2=10
10+5=15
y-intercept=15
So, the full equation of the line would be:
y=-5x+15
