-1/6 The x is coefficient is negative and is 1/6
Your classmate is correct, though this is not explicitly what the midpoint formula is necessarily set out to do. If one is given two sets of endpoints, one can discover the midpoint by finding the mean distance between these two endpoints. For example, if two points are 10 and 2, all you need do to find the midpoint is add the two poles and divide them by 2 (that is, find the average). The same applies for coordinate geometry, except with additional variables, the formula to find the coordinates of a midpoint is: M= (x1+x2/2, y1+y2/2). Thus, two averages (of both the x coordinates and y coordinates are taken). Your classmate is correct if two endpoints are given, think of a line with two poles, the middle of this line must be the midpoint.

<u>Trigonometric Formulas</u>
To solve this problem, we must recall some basic relations and concepts.
The main trigonometric identity relates the sine to the cosine:
The tangent can be found by
The cosine and the secant are related by
They both have the same sign.
The sine is positive in the first and second quadrants, the cosine is positive in the first and fourth quadrants.
The sine is negative in the third and fourth quadrants, the cosine is negative in the second and third quadrants.
We are given
Find the cosine by solving
We have placed the negative sign because we know the secant ('sex') is negative and they both have the same sign.
Now compute the tangent
Rationalizing
Hi there!
81x - 122 = 22
Add 122 to both sides
81x = 144
Divide 81 from both sides
x = 144/81
Simplify
x = 16/9 or 1.78
Hope this helped!
