Answer:
This is a right triangle :)
slope = rise over run = y/x
A (-1,3) slope = 3/-1 = -3
B (1,2) slope = 2/1 = 2
C (-3,-1) slope = -1/-3 = 1/3
2 lines need to be negative reciprocals in order to be a right triangle
negative reciprocal of -3 is 1/3
so this is a right triangle
Step-by-step explanation:
For example, if f(x) = 2x + 7
then f(-3) = 2(-3) + 7
f(-3) = 1
C
10/3 = 3.33
3.3 = 3.3
pie =3.14
square root of 8 =2.8
