Yes but a vertical line cannot because the slope m is undefined.
ACE. Just find the difference between the numbers, and divide the numerator and denominator by it to see if you get 3/4
Answer:
slope = -
Step-by-step explanation:
Differentiating implicitly with respect to x
2x + 2y = 0
2y = - 2x
= - = -
is the measure of the slope of the tangent
rearrange equation to find corresponding y-coordinate of x = - 2
y² = 16 - 4 = 12 = 2 ⇒ y = ± 2
using x = - 2, y = - 2, then
= - = -
