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 y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you write a linear equation in point-slope form?

Back

The point-slope form of a linear equation is written as y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope.

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the rise over run (change in y over change in x).

How do you find the total cost of renting multiple items?

Back

To find the total cost, multiply the number of items rented by the cost per item and add any fixed costs.

Front

What is the formula for calculating the cost of business cards?

Back

The cost can be calculated using a linear equation based on the number of cards ordered and the price per card.

Front

How do you solve a linear equation?

Back

To solve a linear equation, isolate the variable on one side of the equation using inverse operations.

Front

What does the y-intercept represent in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, representing the value of y when x is 0.

Front

What is the significance of the slope in real-world problems?

Back

The slope represents the rate of change, indicating how one quantity changes in relation to another.

Front

How do you determine the number of items you can afford given a budget?

Back

Set up a linear equation based on the total cost and budget, then solve for the number of items.

Front

What is a scatter plot?

Back

A scatter plot is a graph that shows the relationship between two variables using dots to represent data points.
