8th Grade Chapter 4 Review

Front

What is the initial value in a weight loss graph?

Back

The initial value is the starting weight before any weight loss occurs.

Front

What does the slope of a linear equation represent?

Back

The slope represents the rate of change between the variables in the equation.

Front

How do you find the rate of change (slope) between two points?

Back

Use the formula: (y2 - y1) / (x2 - x1).

Front

What is the equation for a linear relationship?

Back

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

Front

What is the range in a set of data?

Back

The range is the set of all possible output values (y-values) of a function.

Front

If Pablo has $12 and earns $7 per lawn, how do you express his total money after mowing x lawns?

Back

The equation is y = 7x + 12.

Front

What does a greater rate of change indicate in a linear function?

Back

It indicates that the output value increases more rapidly with respect to the input value.

Front

What is the meaning of 'linear relationship'?

Back

A linear relationship is a relationship that can be graphically represented as a straight line.

Front

What is the difference between domain and range?

Back

Domain refers to all possible input values (x-values), while range refers to all possible output values (y-values).

Front

How do you determine the initial value from a graph?

Back

The initial value is found at the point where the graph intersects the y-axis.
