Answer:
Only A, the first equation is true.
Step-by-step explanation:
A. (y + 6)(y – 7) + 42 = y² + 6y –7y – 42 + 42 = y² – y. This means A is true
B. (x + 3)(X – 8) = x² + 3x – 8x – 24 = x² – 5x – 24. This means B is false.
Answer:
slope = - 3
Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (- 6, 6) and (x₂, y₂ ) = (- 3, - 3)
m = 
= 
= 
= - 3
