Introduction

In mathematics, equations can be represented in various forms, each with its own unique characteristics and applications. Identifying the form of an equation is crucial in solving problems, understanding mathematical concepts, and applying them to real-world scenarios. In this article, we will explore the forms of equations in questions one through three and discuss the importance of identifying these forms.

Equation 1: y = -2/3x + 4

The first equation is y = -2/3x + 4. This equation is in the slope-intercept form, which is a fundamental form of linear equations. The slope-intercept form is represented as y = mx + b, where m is the slope and b is the y-intercept.

Slope (m): The slope of the equation is -2/3, which means that for every unit increase in x, y decreases by 2/3 units.
Y-intercept (b): The y-intercept is 4, which means that the line intersects the y-axis at the point (0, 4).

To identify the form of this equation, we need to look for the slope and y-intercept. The presence of the slope (m) and y-intercept (b) in the equation indicates that it is in the slope-intercept form.

Equation 2: y = 4(x - 2)

The second equation is y = 4(x - 2). This equation is in the standard form, which is another fundamental form of linear equations. The standard form is represented as ax + by = c, where a, b, and c are constants.

Coefficients (a and b): The coefficients of x and y are 4 and 0, respectively.
Constant term (c): The constant term is -8, which is obtained by multiplying the coefficient of x (4) by the value inside the parentheses (-2).

To identify the form of this equation, we need to look for the coefficients of x and y, as well as the constant term. The presence of these terms in the equation indicates that it is in the standard form.

Equation 3: 3x - 2y = 8

The third equation is 3x - 2y = 8. This equation is in the general form, which is a more general form of linear equations. The general form is represented as ax + by = c, where a, b, and c are constants.

Coefficients (a and b): The coefficients of x and y are 3 and -2, respectively.
Constant term (c): The constant term is 8.
