What is the equation in point-slope form of the line that passes through the points (7, 5)(7, 5) and (−4, −1)(−4, −1) ? y+4=116(
x+1)y+4=116(x+1) y−1=611(x−4)y−1=611(x−4) y+1=611(x+4)y+1=611(x+4) y+1=67(x+4)

Answer:
see explanation
Step-by-step explanation:
Note that (x² + 5)(x² - 5) are the factors of a difference of squares
a² - b² = (a + b)(a - b)
with a = x² and b = 5, hence
(x² + 5)(x² - 5) = (x²)² - 5² = - 25, thus
3( - 25) = 3
- 75
