Answer:
I'm pretty sure I got this right= x = -17
Step-by-step explanation:
So, I just took away -8x from -9x to get -1
the sum looks like this now: -1+3=20.
Now, opposite of +3 is -3 so +3 cancels out -3.
Then you take that -3 and take 3 away from 20.
The sum is this now: -1x =17
Now, divide -1 from -1x and it gives you x.
Then divide -1 from 17 and it gets you to -17
The answer is then, x = -17
I hope U got that right for you!

Answer:
Step-by-step explanation:
This is a very interesting problem. We are given the slope and one point, which makes this funner than normal ;)
Filling in the slope formula with what we are given:
which simplifies to
![-\frac{3}{5}=\frac{y-2}{x+3}](https://tex.z-dn.net/?f=-%5Cfrac%7B3%7D%7B5%7D%3D%5Cfrac%7By-2%7D%7Bx%2B3%7D)
Since slope is rise over run, the rise number is -3; the run number is 5. That means that the equation to find the y coordinate comes from -3 = y - 2; the equation to find the x coordinate comes from 5 = x + 3 (keep in mind that you could have made the x coordinate the negative one; it doesn't matter. You will get the same answer regardless...promise).
Solving for y:
-3 = y - 2 and
y = -1
Solving for x:
5 = x + 3 and
x = 2
Let's check those coordinates in the slope formula and see if our slope is in fact -3/5:
so we're all good!
The coordinates of B are (2, -1)
