Find the slope of a line through (4, 5) and (4, -5). Determine if the line is vertical, horizontal, or neither.

Answer:

Vertical

Slope cannot be determined

Step-by-step explanation:

To find the slope, we are going to use the slope equation as follows

m = (y2-y1)/(x2-x1)

(x1,y1) = (4,5)

(x2,y2) = (4,-5)

m = (-5-5)/(4-4)

This gives an undefined answer and thus we cannot hate the slope value

Looking at the x-axis coordinates, we can see that the difference is just the y axis coordinates and as such we can confirm that the line is vertical

Name the ordered pair that corresponds to an angle of a pi radians
olga2289 [7]

Answer:

3π (540°) and 5π(900°)

Step-by-step explanation:

π radian = 180° degree

in the trigonimitrical cercle each point is taken by many values

so π position is also -π position

to move from π to -π you should move 360° (wich is 2π) backwards

π-2π = π

so  -π = π +2π

you can get as much as you can of values similar to π using the formula :

π + 2*k*π where k is a relative number

  • k=1

π+ 2*1*π = 3π

  • k=2

π+2*2*π = 5π

3π is 540°

5π is 900°

Point K is on line segment JL. Given KL = 2x – 2, JL = 4x + 9, and
sergeinik [125]

Answer:

JL = 21

Step-by-step explanation:

Given that K is on line segment JL, therefore:

KL + JK = JL (according to segment addition postulate)

KL = 2x - 2

JK = 5x + 2

JL = 4x + 9

Thus:

(2x - 2) + (5x + 2) = (4x + 9)

Solve for x

2x - 2 + 5x + 2 = 4x + 9

2x +5x - 2 + 2 = 4x + 9

7x = 4x + 9

Subtract 4x from both sides

7x - 4x = 4x + 9 - 4x

3x = 9

Divide both sides by 3

\frac{3x}{3} = \frac{9}{3}

x = 3

Find the numerical length of JL

JL = 4x + 9

Plug in the value of x

JL = 4(3) + 9 = 12 + 9 = 21
