Answer:
slope is ![-\frac{3}{4}](https://tex.z-dn.net/?f=-%5Cfrac%7B3%7D%7B4%7D)
Step-by-step explanation:
1,-1 -3,2 are two points on the graph
the equation to find slope is ![\frac{y_{1}- y_{2} }{x_{1}- x_{2} }](https://tex.z-dn.net/?f=%5Cfrac%7By_%7B1%7D-%20y_%7B2%7D%20%7D%7Bx_%7B1%7D-%20x_%7B2%7D%20%7D)
so ![\frac{2--1}{-3-1} = -\frac{3}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B2--1%7D%7B-3-1%7D%20%3D%20-%5Cfrac%7B3%7D%7B4%7D)
or you can count how many places it changed in the equation ![\frac{rise}{run}](https://tex.z-dn.net/?f=%5Cfrac%7Brise%7D%7Brun%7D)

Answer:
y=4x-8.5
Step-by-step explanation:
Use point- slope form, since you are given one point and one slope.
y-y₁=m(x-x₁)
Plug coordinates and slope in.
y-(-1/2)=4(x-2)
Solve
y+1/2=4x-8
y=4x-8.5
If it’s 3% that’s 36% a year which means 360% in ten years. $2000+360%=$9200

Explanation:</h2>
The vertex form of the equation of a parabola is given by the following form:
![f(x)=a(x-h)^2+k \\ \\ Where: \\ \\ a:Leading \ Coefficient \\ \\ (h,k):Vertex \ of \ the \ parabola](https://tex.z-dn.net/?f=f%28x%29%3Da%28x-h%29%5E2%2Bk%20%5C%5C%20%5C%5C%20Where%3A%20%5C%5C%20%5C%5C%20a%3ALeading%20%5C%20Coefficient%20%5C%5C%20%5C%5C%20%28h%2Ck%29%3AVertex%20%5C%20of%20%5C%20the%20%5C%20parabola)
In this exercise, we have the following equation:
![y=-(x-2)^2+3](https://tex.z-dn.net/?f=y%3D-%28x-2%29%5E2%2B3)
From here, we can conclude that:
![Leading \ coefficient: \ -1 \\ \\ Vertex: \ (2,3)](https://tex.z-dn.net/?f=Leading%20%5C%20coefficient%3A%20%5C%20-1%20%5C%5C%20%5C%5C%20Vertex%3A%20%5C%20%282%2C3%29)
Since the leading coefficient is less than zero, the parabola open downward. So, the graph is shown below and the vertex has been indicated.
