(MCA) Test 3

Front

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

What does the slope of a line represent?

Back

The slope represents the rate of change of y with respect to x, indicating how steep the line is.

Front

How do you identify the slope from the equation y = mx + b?

Back

The slope is the coefficient 'm' in the slope-intercept form of the equation.

Front

What is the slope-intercept form of a linear equation?

Back

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

Front

What does an undefined slope indicate about a line?

Back

An undefined slope indicates a vertical line, which means the x-value does not change.

Front

How can you determine if an equation is in slope-intercept form?

Back

An equation is in slope-intercept form if it can be expressed as y = mx + b, where m and b are constants.

Front

What is the significance of the point (0, b) in a linear equation?

Back

The point (0, b) is the y-intercept, indicating where the line crosses the y-axis.

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

The slope is calculated using the formula (y2 - y1) / (x2 - x1).

Front

What does the term 'linear equation' refer to?

Back

A linear equation is an equation that graphs to a straight line, typically in the form y = mx + b.

Front

What is the relationship between the slope and the direction of a line?

Back

A positive slope indicates the line rises from left to right, while a negative slope indicates it falls from left to right.
