Introduction

In this article, we will explore the concept of solving for missing values in a linear equation. We will use the equation y=32x−2y=\frac{3}{2}x-2 as an example and fill in the missing values in the table. This will help us understand how to work with linear equations and how to use them to solve problems.

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 y=mx+by=mx+b, where mm is the slope and bb is the y-intercept. The equation y=32x−2y=\frac{3}{2}x-2 is a linear equation because it can be written in this form.

The Equation y=32x−2y=\frac{3}{2}x-2

The equation y=32x−2y=\frac{3}{2}x-2 is a linear equation with a slope of 32\frac{3}{2} and a y-intercept of -2. This means that for every 1 unit increase in xx, yy will increase by 32\frac{3}{2} units.

Filling in the Missing Values

Now that we understand the equation y=32x−2y=\frac{3}{2}x-2, we can fill in the missing values in the table.

Table

x y
-2 a
-1 b
0 c
1 d
2 e

To fill in the missing values, we can plug in the values of xx into the equation y=32x−2y=\frac{3}{2}x-2 and solve for yy.

Solving for yy

  • For x=−2x=-2, we have: y=32(−2)−2=−6y=\frac{3}{2}(-2)-2=-6
  • For x=−1x=-1, we have: y=32(−1)−2=−3y=\frac{3}{2}(-1)-2=-3
  • For x=0x=0, we have: y=32(0)−2=−2y=\frac{3}{2}(0)-2=-2
  • For x=1x=1, we have: y=32(1)−2=−12y=\frac{3}{2}(1)-2=-\frac{1}{2}
  • For x=2x=2, we have: y=32(2)−2=1y=\frac{3}{2}(2)-2=1
