Mathematics
1 answer:
Leto [7]3 years ago
3 0

Answer:

cos(71)

Step-by-step explanation:

Since 19° is less than 90, we can express this in terms of confunction.

sin(θ) = cos(90-θ)

sin(19) = cos(90-19)

sin(19) = cos(71)

Select the equation of the line to the equation y=-4x-6 and that passes through the point (1,2)
omeli [17]
I don't see a list of options, but I know that the answer is y = -4x + 6.

Point - Slope Form: y - y₁ = m(x - x₁)

y - 2 = -4(x - 1)

y - 2 = -4x + 4
  + 2          + 2
--------------------
y = -4x + 6
