What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the ratio of the change in the y-values to the change in the x-values between two points on the line.

How do you calculate the average cost per item?

Back

To calculate the average cost per item, divide the total cost by the number of items. For example, if 15 lunches cost $33.75, the average cost per lunch is $33.75 / 15 = $2.25.

What is a linear relationship?

Back

A linear relationship is a relationship between two variables that can be represented by a straight line on a graph, typically expressed in the form y = mx + b, where m is the slope and b is the y-intercept.

How do you find the total cost when there is a fixed fee and a variable cost?

Back

The total cost can be found using the equation c = fixed fee + (variable cost per item * number of items). For example, if the fixed fee is $24 and the variable cost is $8 per shirt, the total cost for k shirts is c = 24 + 8k.

What is the ratio of two quantities?

Back

The ratio of two quantities is a comparison of the two amounts, expressed as a fraction or a relationship. For example, the ratio of orange juice to pineapple juice in a bottle can be expressed as the amount of orange juice divided by the amount of pineapple juice.

What is the significance of the y-intercept 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

How do you determine if two lines are parallel?

Back

Two lines are parallel if they have the same slope but different y-intercepts.
