Standard Form Word Problems

Front

What is Standard Form in linear equations?

Back

Standard Form is a way of writing linear equations in the format Ax + By = C, where A, B, and C are integers, and A should be non-negative.

How do you identify variables in a word problem?

Back

Variables are typically represented by letters (like x and y) and represent unknown quantities that you need to solve for in the problem.

Front

What does the term 'linear function' mean?

Back

A linear function is a function that graphs to a straight line, which can be expressed in the form y = mx + b, where m is the slope and b is the y-intercept.

Front

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

Back

Identify the quantities involved, assign variables, and translate the relationships and conditions described in the problem into an equation.

Front

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

Back

Coefficients represent the rate of change or the cost per unit in a word problem, indicating how much one variable affects the other.

Front

What does it mean to solve for a variable in an equation?

Back

Solving for a variable means isolating that variable on one side of the equation to find its value.

Front

How do you check if your linear equation is correct?

Back

Substitute the values of the variables back into the original equation to see if both sides are equal.

Front

What is the relationship between the slope and the y-intercept in a linear equation?

Back

The slope indicates the steepness of the line, while the y-intercept is the point where the line crosses the y-axis.

Front

How can you represent a real-world scenario with a linear equation?

Back

By identifying the quantities involved, determining their relationships, and expressing them in the form of a linear equation.

Front

What is the first step in solving a word problem involving a linear equation?

Back
