Plot this on the Cartesian Graph:


Determine the abcissa for (9,8)

Abcissa = absolute value of x-value
Perpendicular distance to the y-axis
Abcissa = |9| = 9

Determine the ordinate for (9,8)

Ordinate = absolute value of y-value
Perpendicular distance to the x-axis
Ordinate = |8| = 8

Evaluate the ordered pair (9,8)

We start at the coordinates (0,0)
Since our x coordinate of 9 is positive
We move up on the graph 9 space(s)
Since our y coordinate of 8 is positive
We move right on the graph 8 space(s)

Determine the quadrant for (9,8)

Since 9>0 and 8>0
(9,8) is in Quadrant I

Convert the point (9,8°) from
polar to Cartesian

The formula for this is below:

Polar Coordinates are (r,θ)
Cartesian Coordinates are (x,y)
Polar to Cartesian Transformation is
(r,θ) → (x,y) = (rcosθ,rsinθ)
(r,θ) = (9,8°)
(rcosθ,rsinθ) = (9cos(8),9sin(8))
(rcosθ,rsinθ) = (9(0.99026806876377),9(0.13917310080207))
(rcosθ,rsinθ) = (8.9124,1.2526)
(9,8°) = (8.9124,1.2526)

Determine the quadrant for (8.9124,1.2526)

Since 8.9124>0 and 1.2526>0
(8.9124,1.2526) is in Quadrant I

Convert (9,8) to polar

Cartesian Coordinates are denoted as (x,y)
Polar Coordinates are denoted as (r,θ)
(x,y) = (9,8)

Transform r:

r = ±√x2 + y2
r = ±√92 + 82
r = ±√81 + 64
r = ±√145
r = ±12.041594578792

Transform θ

θ = tan-1(y/x)
θ = tan-1(8/9)
θ = tan-1(0.88888888888889)
θradians = 0.72664234068173

Convert our angle to degrees

Angle in Degrees  =  Angle in Radians * 180
  π

θdegrees  =  0.72664234068173 * 180
  π

θdegrees  =  130.79562132271
  π

θdegrees = 41.63°
Therefore, (9,8) = (12.041594578792,41.63°)

Determine the quadrant for (9,8)

Since 9>0 and 8>0
(9,8) is in Quadrant I

Show equivalent coordinates

We add 360°
(9,8° + 360°)
(9,368°)

(9,8° + 360°)
(9,728°)

(9,8° + 360°)
(9,1088°)

Method 2: -(r) + 180°

(-1 * 9,8° + 180°)
(-9,188°)

Method 3: -(r) - 180°

(-1 * 9,8° - 180°)
(-9,-172°)

Determine symmetric point

If (x,y) is symmetric to the origin:
then the point (-x,-y) is also on the graph
(-9, -8)

Determine symmetric point

If (x,y) is symmetric to the x-axis:
then the point (x, -y) is also on the graph
(9, -8)

Determine symmetric point

If (x,y) is symmetric to the y-axis:
then the point (-x, y) is also on the graph
(-9, 8)

Take (9, 8) and rotate 90 degrees
We call this R90°

The formula for rotating a point 90° is:
R90°(x, y) = (-y, x)
R90°(9, 8) = (-(8), 9)
R90°(9, 8) = (-8, 9)

Take (9, 8) and rotate 180 degrees
We call this R180°

The formula for rotating a point 180° is:
R180°(x, y) = (-x, -y)
R180°(9, 8) = (-(9), -(8))
R180°(9, 8) = (-9, -8)

Take (9, 8) and rotate 270 degrees
We call this R270°

The formula for rotating a point 270° is:
R270°(x, y) = (y, -x)
R270°(9, 8) = (8, -(9))
R270°(9, 8) = (8, -9)

Take (9, 8) and reflect over the origin
We call this rorigin

Formula for reflecting over the origin is:
rorigin(x, y) = (-x, -y)
rorigin(9, 8) = (-(9), -(8))
rorigin(9, 8) = (-9, -8)

Take (9, 8) and reflect over the y-axis
We call this ry-axis

Formula for reflecting over the y-axis is:
ry-axis(x, y) = (-x, y)
ry-axis(9, 8) = (-(9), 8)
ry-axis(9, 8) = (-9, 8)

Take (9, 8) and reflect over the x-axis
We call this rx-axis

Formula for reflecting over the x-axis is:
rx-axis(x, y) = (x, -y)
rx-axis(9, 8) = (9, -(8))
rx-axis(9, 8) = (9, -8)

A pair of numbers signifying the location of a point
(x, y)
point
an exact location in the space, and has no length, width, or thickness
