Algebra Topic 2: Linear Equations

Front

What does the y-intercept represent in a linear equation?

Back

The y-intercept represents the value of y when x is 0, indicating the starting point of the line on the y-axis.

Front

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

Back

Front

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

Front

What is the standard form of a linear equation?

Back

Front

What does the x-intercept represent in a linear equation?

Back

The x-intercept represents the value of x when y is 0, indicating where the line crosses the x-axis.

Front

How can you convert a linear equation from slope-intercept form to standard form?

Back

Front

What is the slope of a line that is horizontal?

Back

The slope of a horizontal line is 0, indicating that there is no change in y as x changes.

Front

What is the slope of a line that is vertical?

Back

The slope of a vertical line is undefined, as it cannot be expressed as a ratio of change in y to change in x.

Front

How do you determine if two lines are parallel?

Back

Two lines are parallel if they have the same slope but different y-intercepts.

Front

How do you determine if two lines are perpendicular?

Back

Two lines are perpendicular if the product of their slopes is -1.
