1 answer:

3 0

4 - 3 (4) = 1

4(3) + 5(3) = 4

4 - 3(4) = 1

4 - 12 = 1

-8 = 1

4(3) + 5(3) = 4

12 + 15 = 4

27 = 4

Your answers are: -8 = 1, and 27 = 4.

Answer:

Option B

Step-by-step explanation:

The slope of the line BC is,

$\frac{ - 2 - 8}{7 - 3}$

$= \frac{ - 10}{4} = - \frac{5}{2}$

Since AD is altitude to BC, we can say AD is perpendicular to BC, so the slope of the line AD which is perpendicular line to BC will be,

$\frac{2}{5}$
