Qzz: Unit 3 Review

Front

What is the formula to find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

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

Front

What is the significance of the y-intercept in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, representing the value of y when x = 0.

Front

What is the general form of a linear equation?

Back

The general form of a linear equation is Ax + By = C, where A, B, and C are constants.

Front

How can you determine if a point lies on a line represented by a linear equation?

Back

Substitute the x and y coordinates of the point into the equation. If the equation holds true, the point lies on the line.

Front

What is the relationship between the slopes of two lines that are perpendicular?

Back

The slopes of two perpendicular lines are negative reciprocals of each other, meaning if one slope is m, the other is -1/m.

Front

What is the process for finding the x-intercept of a linear equation?

Back

To find the x-intercept, set y = 0 in the equation and solve for x.

Front

What does the term 'application-based question' refer to in mathematics?

Back

Application-based questions require students to apply mathematical concepts and techniques to solve real-world problems.

Front

How do you interpret the slope of a line in a real-world context?

Back

The slope represents the rate of change between the two variables represented by the axes.
