Front

What is the equation of a line in slope-intercept form?

Back

The equation of a line in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you calculate the total cost of an item with a service fee of 10%?

Back

To calculate the total cost, use the expression z + 0.10z, which simplifies to 1.10z.

Front

What does a 15% discount on an item mean?

Back

A 15% discount means you pay 85% of the original price, represented by the expression y - 0.15y, which simplifies to 0.85y.

Front

What is the equivalent expression for 5x - 2y?

Back

The expression 5x - 2y can be rewritten as 10x - 3y + 1(-5x + y) by finding the appropriate value for the question mark.

Front

What is the slope of the line represented by the equation y = 2x + 3?

Back

The slope of the line is 2.

Front

What does the term 'slope' refer to in a linear equation?

Back

The slope refers to the steepness of the line, indicating how much y changes for a unit change in x.

Front

How do you find the y-intercept of a linear equation?

Back

The y-intercept can be found by setting x to 0 in the equation and solving for y.

Front

What is the formula to calculate the total cost including tax?

Back

The total cost including tax can be calculated using the formula: Total Cost = Price + (Tax Rate * Price).

Front

What is the difference between a discount and a markup?

Back

A discount reduces the price of an item, while a markup increases the price.

Front

How can you express a 10% increase in a price z?

Back

A 10% increase in price z can be expressed as z + 0.10z, which simplifies to 1.10z.
