6th Honors Unit 4 Test Review

Front

What are dependent quantities?

Back

Dependent quantities are values that depend on other values. For example, in a relationship where y depends on x, the values of y change based on the values of x.

Front

Identify the dependent quantities from the list: 0, 1, 2, 3, 4, 5; 0, 5, 10, 15, 20; 10, 20, 60, 80, 100.

Back

The dependent quantities are 0, 5, 10, 15, 20.

Front

What does the equation y = x - 2 represent?

Back

The equation y = x - 2 means that for every value of x, the value of y is 2 less than x.

Front

What does the equation y = 2x represent?

Back

The equation y = 2x means that for every value of x, the value of y is twice the value of x.

Front

How do you describe the relationship between y = x - 2 and y = 2x?

Back

In y = x - 2, y is 2 less than x; in y = 2x, y is twice the value of x.

Front

What is the general form of a linear equation?

Back

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

Front

What is a slope in a linear equation?

Back

The slope (m) represents the rate of change of y with respect to x. It indicates how steep the line is.

Front

What is a y-intercept in a linear equation?

Back

The y-intercept (b) is the value of y when x is 0. It is the point where the line crosses the y-axis.

Front

How can you represent a rate of change in an equation?

Back

A rate of change can be represented as a fraction or a decimal in an equation, such as y = mx, where m is the rate.

Front

If Jose travels at a rate of 0.25 miles per minute, what equation represents this relationship?

Back

The equation is y = \frac{1}{4}x, where y is the distance traveled and x is the time in minutes.
