Answer:
6
Step 1: Solve Square Root
Vx+3=x-3
x+3=(x-3)^2 (squared both sides)
x+3=x^2-6x+9
x+3-(x^2-6x+9)=0
(-x+1)(x-6)=0 (factor left side of equation)
-x+1=0 or x-6=0
x=1 or x=6
When you plug it in to check
1 (Doesn't Work)
6 (Work)
Therefore, 6 is your solution.

Step-by-step explanation:
☆Remember:
![m = \frac{y_2 - y_1}{x_2 - x_1}](https://tex.z-dn.net/?f=m%20%3D%20%20%5Cfrac%7By_2%20-%20y_1%7D%7Bx_2%20-%20x_1%7D%20)
☆Just plug it in with 2 sets of coordinate points.
![m = \frac{7 - 3}{9 - 1} = \frac{4}{8} = \frac{1}{2}](https://tex.z-dn.net/?f=m%20%3D%20%20%5Cfrac%7B7%20-%203%7D%7B9%20-%201%7D%20%3D%20%20%5Cfrac%7B4%7D%7B8%7D%20%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20)
This equation is written in <em>standard form</em>, so we need to change it into <em>slope-intercept form.</em>
<em />
3x = -y - 5
3x + y = -y + y - 5
3x + y = -5
3x - 3x + y = -5 - 3x
y = -5 - 3x
y = -3x - 5
The slope is classified as "m" in this type of equation, so, the slope is -3.
Best of Luck!
