Step-by-step explanation:
The slope-intercept form of the first equation is
The slope-intercept form of the first equation isy= -4x +5
The slope intercept form of the second equation is
3y-9=-6x
3y= -6x +9
y= -2x+3

Answer:
15n
Step-by-step explanation:
Given
The above table
Required
The formula of the table
First, calculate the slope (m)
![m = \frac{y_2 - y_1}{n_2 - n_1}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7By_2%20-%20y_1%7D%7Bn_2%20-%20n_1%7D)
Where:
<em>n = Number of Lawns</em>
<em>y = Earnings</em>
![(n_1,y_1) = (2,30)](https://tex.z-dn.net/?f=%28n_1%2Cy_1%29%20%3D%20%282%2C30%29)
![(n_2,y_2) = (5,75)](https://tex.z-dn.net/?f=%28n_2%2Cy_2%29%20%3D%20%285%2C75%29)
So, we have:
![m = \frac{75 - 30}{5 - 2}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B75%20-%2030%7D%7B5%20-%202%7D)
![m = \frac{45}{3}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B45%7D%7B3%7D)
![m = 15](https://tex.z-dn.net/?f=m%20%3D%2015)
The equation is then calculated as:
![y = m(n- n_1) + y_1](https://tex.z-dn.net/?f=y%20%3D%20m%28n-%20n_1%29%20%2B%20y_1)
This gives:
![y = 15(n- 2) + 30](https://tex.z-dn.net/?f=y%20%3D%2015%28n-%202%29%20%2B%2030)
![y = 15n- 30 + 30](https://tex.z-dn.net/?f=y%20%3D%2015n-%2030%20%2B%2030)
![y = 15n](https://tex.z-dn.net/?f=y%20%3D%2015n)
Hence:
<em>B is correct</em>
The correct answer should 1.1333
Y2-Y1 or X2-X1 is the formula
9-4/1-0
It would be undefined
