Answer:
y = x + 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = , thus
y = x + c ← is the partial equation
To find c substitute (- 2, - 1) into the partial equation
- 1 = - 5 + c ⇒ c = - 1 + 5 = 4
y = x + 4 ← equation of line

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
= -
= -
