What is a linear equation?

Back

A linear equation is an equation that makes a straight line when graphed. It can be written in the form Ax + By = C, where A, B, and C are constants.

What does it mean to write an equation in standard form?

Back

Standard form of a linear equation is Ax + By = C, where A, B, and C are integers, and A should be non-negative.

How do you represent a total cost equation for a rental service?

Back

The total cost can be represented as y = fixed fee + (hourly rate * number of hours), where y is the total cost.

What is the significance of the slope in a linear equation?

Back

The slope indicates the rate of change of the dependent variable with respect to the independent variable. It shows how much y changes for a unit change in x.

How do you convert a word problem into a linear equation?

Back

Identify the variables, determine the relationships between them, and express these relationships using an equation.

Front

What is the meaning of the y-intercept in a linear equation?

Back

The y-intercept is the value of y when x is 0. It represents the starting point of the line on the y-axis.

How do you write an equation for a budget constraint?

Back

The equation can be written as total budget = (cost per item * number of items) + (cost per another item * number of another items).

What is the difference between an equation and an inequality?

Back

An equation states that two expressions are equal, while an inequality shows that one expression is greater than, less than, or not equal to another.

Front

How do you interpret the solution of a linear equation in a real-world context?

Back

The solution represents the values of the variables that satisfy the conditions of the problem, often indicating feasible options or limits.

Front

What is the role of coefficients in a linear equation?

Back

Coefficients represent the rate at which the dependent variable changes with respect to the independent variable.
