Algebra 1 Chapter 4 Test Review A

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

How do you find the slope of a line given two points?

Back

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

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

What does it mean for two lines to be perpendicular?

Back

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

Front

Given the equation y = 2x + 3, what is the slope?

Back

The slope is 2.

Front

Given the equation y = -\frac{4}{3}x - 1, what is the y-intercept?

Back

The y-intercept is -1.

Front

How do you convert the standard form of a line to slope-intercept form?

Back

Rearrange the equation Ax + By = C to solve for y in terms of x.

Front

What is the slope of the line that passes through the points (-11, 5) and (-6, 1)?

Back

The slope is -\frac{4}{5}.

Front

What is the y-intercept of the line described by the equation y = -x + 4?

Back

The y-intercept is 4.

Front

If a line has a slope of 3, what is the slope of a line parallel to it?

Back

The slope of a parallel line is also 3.
