An ordered pair such as (3,-1), is a shorthand way of writing two variables, such as x = 3 and y = -1. The order of the numbers in the pair is important: x always comes before y.
An ordered pair is a composition of the x coordinate (abscissa) and the y coordinate (ordinate), having two values written in a fixed order within parentheses.
It helps to locate a point on the Cartesian plane for better visual comprehension.
The numeric values in an ordered pair can be integers or fractions.
Ordered Pair = (x,y)
Where, x = abscissa, the distance measure of a point from the primary axis “x”
And, y = ordinate, the distance measure of a point from the secondary axis “y”
In the Cartesian plane, we define a two-dimensional space with two perpendicular reference lines, namely x-axis and y-axis. The point where the two lines meet at “0” is the origin.

Answer:
x=8
Step-by-step explanation:
distribute 7(4+x)
28+7x=84
84-28=56
56/7=8

Answer:
b =
Step-by-step explanation:
Using the discriminant for nature of roots ( x- intercepts )
If b² - 4ac = 0 then roots are real and equal ( that is only 1 x- intercept )
Given
f(x) = x² - 2bx + b² + 2b - 1
with a = 1, b = - 2b and c = b² + 2b - 1, then
(- 2b)² - 4(b² + 2b - 1) = 0 ← distribute and simplify left side
4b² - 4b² - 8b + 4 = 0
- 8b + 4 = 0 ( subtract 4 from both sides )
- 8b = - 4 ( divide both sides by - 8 )
b =
The answer is c because a is a letter, b is never ending, and d is a fraction with pi in it
