Answer:
B -3.
Step-by-step explanation:
The slope = (y2-y1)/(x2-x1)
= (-2-4)/(8-6)
= -6/2
= -3.

Step-by-step explanation:
Slope formula
Answer:
f(x) = (x-4)² + 1Step-by-step explanation:
For clarity, exponents should be marked with a ^: f(x) = x^2 - 8x + 17
Group like terms
f(x) = (x² - 8x) + 17
Complete the square
coefficient of x term: -8
divide coefficient in half: -4
square the result: (-4)² = 4²
use 4² to complete the square and keep the equation balanced:
f(x) = (x² - 8x + 4²) - 4² + 17
f(x) = (x-4)² + 1
