Answer:
y - 1 = - 4(x + 3)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = - 4 and (a, b) = (- 3, 1), thus
y - 1 = - 4(x - (- 3)), that is
y - 1 = - 4(x + 3)
Answer:
all positive numbers
Step-by-step explanation:
The domain is all of the possible x coordinates. Since we are doing a square root, the answer can't be negative, so if we are multiplying x by a positive number, x can't be negative. All other numbers would work.
Answer:
use cosine law
