What is the y-intercept of a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, represented as (0, b) in the equation y = mx + b.

Front

How do you find the slope of a line from its equation?

Back

The slope (m) can be found in the slope-intercept form of the equation y = mx + b, where m is the coefficient of x.

Front

What is the slope of the line represented by the equation y = 10?

Back

The slope is 0, indicating a horizontal line.

Front

What does a slope of -4 indicate about a line?

Back

A slope of -4 indicates that for every 1 unit increase in x, y decreases by 4 units, resulting in a downward slant.

Front

How do you write an equation from a word problem?

Back

Identify the variables, determine the relationship, and express it in the form y = mx + b.

Front

What is the y-intercept of the equation y = 2x + 5?

Back

The y-intercept is (0, 5).

Front

What does the term 'slope' refer to in mathematics?

Back

Slope refers to the steepness or incline of a line, calculated as the rise over run.

Front

What is the general form of a linear equation?

Back

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

Front

If a line has a slope of 0, what does that mean?

Back

It means the line is horizontal and does not rise or fall as x changes.

Front

What is the significance of the y-intercept in a graph?

Back

The y-intercept indicates the starting value of y when x is 0.
