Part 2 Review Test: Algebra II S1 Finals (2024 - 2025)

Front

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

Back

The point-slope form is given by the equation: y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope.

Front

How do you find the slope from a point-slope equation?

Back

In the equation y + 1 = -3(x - 5), the slope (m) is the coefficient of (x), which is -3.

Front

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

Back

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

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope and will never intersect.

Front

If the slope of a line is m = 4, what is the slope of a line parallel to it?

Back

The slope of a line parallel to it is also 4.

Front

What is the formula for calculating the slope between two points (x1, y1) and (x2, y2)?

Back

The formula for slope is m = (y2 - y1) / (x2 - x1).

Front

What is a line of best fit?

Back

A line of best fit is a straight line that best represents the data on a scatter plot, minimizing the distance between the line and all data points.

Front

How do you convert from point-slope form to slope-intercept form?

Back

To convert, solve for y in the point-slope equation: y - y1 = m(x - x1) to get y = mx + b.

Front

What is the y-intercept in the equation y = 2x + 3?

Back

The y-intercept is the value of y when x = 0, which is 3 in this case.

Front

What is the significance of the slope in a linear equation?

Back

The slope indicates the steepness of the line and the direction it moves; a positive slope rises, while a negative slope falls.
