Introduction

In mathematics, parametric equations are used to describe the relationship between two or more variables. These equations are often used to model real-world phenomena, such as the motion of an object or the behavior of a system. In this article, we will explore the concept of parametric equations and how to find the slope of a line representing the direct relationship between two variables.

What are Parametric Equations?

Parametric equations are a set of equations that describe the relationship between two or more variables. These equations are often used to model real-world phenomena, such as the motion of an object or the behavior of a system. In parametric equations, one variable is used as a parameter, which is a value that is used to determine the value of the other variable.

The Given Parametric Equations

The given parametric equations are:

$x = 5t - 3$
$y = -7 + 4t$

In these equations, $t$ is the parameter, which is a value that is used to determine the value of $x$ and $y$ .

Finding the Slope of the Direct Relationship

To find the slope of the direct relationship between $x$ and $y$ , we need to eliminate the parameter $t$ from the equations. This can be done by solving one of the equations for $t$ and substituting it into the other equation.

Step 1: Solve the First Equation for $t$

We can solve the first equation for $t$ by isolating $t$ on one side of the equation:

$t = \frac{x + 3}{5}$

Step 2: Substitute the Expression for $t$ into the Second Equation

Now that we have an expression for $t$ , we can substitute it into the second equation:

$y = -7 + 4\left(\frac{x + 3}{5}\right)$

$y = -7 + \frac{4(x + 3)}{5}$
