Given:
Triangle Point coordinates or vertices:
A(16,0)
B(9,2)
C(2,0)
Required:
Side with slope -2/7
Solution:
To know which side has the slope required, we need to calculate the slope of each paired point by the two-point slope formula:
m = (y2-y1)/(x2-x1)
We first try points A and B.
m1 = (2-0)/(9-16)
m1 = -2/7
Thus, the side with the slope -2/7 is side AB.

if im right, can you mark me brainliest?
Answer:
30 degrees
Step-by-step explanation:
If you were to draw a number line, 15 and -15 are both 15 units away from 0. So, 15 + 15 =30

Answer: Scalene triangle
Step-by-step explanation:
A Scalene triangle has all of its three lengths to be different. The traingle above can not be an equilateral triangle too because all the sides aren't equal.
Also, it's not an isosceles triangle since two of its sides are not thesame. It's not a right angle triangle as the square of the hypothenuse isn't equal to the addition of the square of the other two sides.
