The chords SR and ST are congruent, so the (minor) arcs SR and ST have the same measure.

The measure of the arcs SR, ST, and RT add up to 360º. So we have

2xº + 64º = 360º ==> x = 148

Equation
--------------------------------------------------------------------------
$y - 9 = - \dfrac{1}{2} (x + 2)$

--------------------------------------------------------------------------
Rearrange the equation
--------------------------------------------------------------------------
$y - 9 = - \dfrac{1}{2} (x + 2) \\ \\
 y - 9 = - \dfrac{1}{2}x - 1 \\ \\
 y - 9 + 9 = - \dfrac{1}{2}x - 1 + 9 \ \Longleftarrow \text{add 9 to both side} \\ \\
 y = -\dfrac{1}{2}x + 8$

slope of the perpendicular line
--------------------------------------------------------------------------
slope = 2

(*the slope of the perpendicular line is the negative reciprocal of the slope of line)

---------------------------------------------------------------------------
Substitute slope into equation y = mx + c
---------------------------------------------------------------------------
y = 2x + c

---------------------------------------------------------------------------
Find y-intercept
---------------------------------------------------------------------------
y = 2x + c
At point (0, 4)
4 = 2(0) + c
c = 4

----------------------------------------------------------------------------
Substitute y-intercept into the equation y = 2x + c
-----------------------------------------------------------------------------
y = 2x + 4

----------------------------------------------------------------------------
Answer: y = 2x + 4
-----------------------------------------------------------------------------

The table represents a linear function. What is the slope of the function?

TEA [102]

Answer:

-4

Step-by-step explanation:

The function is linear; therefore, the slope of the line joining any two points is the same.

We take any two points from the table and compute the slope or rise/ run between them— let is take points (-4, -2) and (-2, -10).

The slope $m$ of the line joining the points is

$m=\dfrac{\Delta y }{\Delta x } =\dfrac{-2-(-10)}{-4-(-2)} \\\\\boxed{m=-4}$

The slope of the function is -4.
