Answer:
Please see below :)
Step-by-step explanation:
The slope is just what's in front of the x!
So:
1.) slope = -1/4
2.) slope = undefined
3.) slope = -9

Hope this helps!
Given:
The vertices of a triangle ABC are A(-3,-4), B(16,-2) and C(13,-10).
To show:
That the triangle ABC is a right angled triangle.
Solution:
Distance formula:

The vertices of a triangle ABC are A(-3,-4), B(16,-2) and C(13,-10).
Using the distance formula, we get




Similarly,


And,


Now, add the square of two smaller sides.




Since the sum of the square of two smaller sides is equal to the square of the largest side, therefore the given triangle is a right angle triangle by using Pythagoras theorem.
Hence proved.
I believe the answer is B but I’m nah for sure
