Answer:
so can you put it more fouces to the answer
Step-by-step explanation:
The value of the expression sec (-π) is equal to -1 if the given expression is undefined.
As given in the question,
Given expression: sec (-π)
Standard position of unit circle: -π is representing semicircle with terminal point on negative x-axis with coordinates (-1, 0)
Hypotenuse = √ (-1)² + 0²
= 1
Value of the expression is given by
sec α = Hypotenuse / Base (x-coordinate)
⇒sec(-π) = 1 / -1
⇒sec(-π) = -1
Therefore, the value of the expression sec (-π) is equal to -1.

The formula for direct variation is y = kx<span> where k </span>≠ 0
y = 9/x is an inverse relation
Answer:
y = 4x -5
Step-by-step explanation:
First, find the slope by subtracting 11 by 3 and 4 by 2. The slope is 8/2, or 4. This is your current equation: y = 4x + b. Plug in one of your coordinates into the equation; it doesn't matter which one. However, I'm going to use the first point so it should look like this: 3 = 4(2) + b. 4 times 2 equals 8, so it should look like this: 3 = 8 + b. Subtract 8 from both sides to get -5 = b. Go back to your original equation and plug in -5 for b. This is your final equation: y = 4x -5. Hope this helped!
