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
Answer:
There would be an overall 25% decrease
Step-by-step explanation:
Because -75 + 50 = -25
Answer:
the answer is fused sentence i believe if thats what your asking
Step-by-step explanation:
Q=1/36 or q=-1/6, for the question
So the formula for the area of a triangle is 
(b = base, h = height). In this case, by counting from (-3,-3) to (-3,2) the height is 5 and the base is 4 counting from (-3,2) to (1,2).
Using this info, we can form the equation
and solve from there.
