Answer:
y = -4x +10
Slope = -4
Step-by-step explanation:
![8x + 2y = 20](https://tex.z-dn.net/?f=8x%20%2B%202y%20%3D%2020)
Slope intercept form =
![y = mx + b](https://tex.z-dn.net/?f=y%20%20%3D%20mx%20%2B%20b)
![2y = - 8x + 20](https://tex.z-dn.net/?f=2y%20%3D%20%20-%208x%20%2B%2020)
Divide both sides of the equation by 2
![\frac{2y}{2} = \frac{ - 8x}{2} + \frac{20}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2y%7D%7B2%7D%20%20%3D%20%20%5Cfrac%7B%20-%208x%7D%7B2%7D%20%20%2B%20%20%5Cfrac%7B20%7D%7B2%7D%20)
Simplify
![y = - 4x + 10](https://tex.z-dn.net/?f=y%20%3D%20%20-%204x%20%2B%2010)
In y= mx+b , m is the slope and the coefficient of x
![m = - 4](https://tex.z-dn.net/?f=m%20%3D%20%20-%204)
Answer:
The number of shots Nick sunk was 8
Step-by-step explanation:
Let
x -----> number of shots that Nick sunk.
y -----> number of shots Nick missed
we know that
x+y=28
y=28-x -----> equation A
5x-2y=0 ----> equation B
substitute equation A in equation B and solve for x
5x-2(28-x)=0
5x-56+2x=0
7x=56
x=8
Find the value of y
y=28-x ----> y=28-8=20
therefore
The number of shots Nick sunk was 8
