Introduction
In mathematics, solving linear equations is a fundamental concept that helps us find the value of unknown variables. When we are given a linear equation and a value for one of the variables, we can use this information to find the corresponding value of the other variable. In this article, we will explore how to use the equation y = 4x - 3
and the value x = 2
to find an ordered pair that is a solution.
Understanding Linear Equations
A linear equation is an equation in which the highest power of the variable(s) is 1. In other words, it is an equation that can be written in the form ax + b = c
, where a
, b
, and c
are constants, and x
is the variable. Linear equations can be solved using various methods, including substitution, elimination, and graphing.
The Equation y = 4x - 3
The equation y = 4x - 3
is a linear equation in which the variable y
is expressed in terms of the variable x
. The coefficient of x
is 4, and the constant term is -3. This equation represents a straight line with a slope of 4 and a y-intercept of -3.
Substituting x = 2
into the Equation
Now that we have the equation y = 4x - 3
, we can substitute the value x = 2
into the equation to find the corresponding value of y
. To do this, we simply replace x
with 2 in the equation:
y = 4(2) - 3
Simplifying the Equation
To simplify the equation, we can multiply 4 and 2 to get 8, and then subtract 3:
y = 8 - 3
y = 5
The Ordered Pair
Now that we have found the value of y
, we can write the ordered pair as (2, 5)
. This means that when x = 2
, the corresponding value of y
is 5.
Conclusion
In this article, we used the equation y = 4x - 3
and the value x = 2
to find an ordered pair that is a solution. We substituted the value of x
into the equation, simplified the resulting expression, and found the value of y
. The ordered pair is (2, 5)
, which means that when x = 2
, the corresponding value of y
is 5.
