Slope and Line Equations Practice

Front

In the equation y=mx+b, what does the m represent?

Back

m represents the slope of the line.

Front

Write the equation of a line PERPENDICULAR to y = -2x + 1 and passes through the point (2, 3).

Back

Front

What slope is parallel to: m = 3/4?

Back

The slope parallel to m = 3/4 is also 3/4.

Front

Using the slope formula, what is the slope of the line that passes through these two points? (1, 4) (3, -2)

Back

The slope is -3.

Front

What is the slope-intercept form of a line?

Back

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

Front

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

Back

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

Front

What is the relationship between the slopes of parallel lines?

Back

Parallel lines have the same slope.

Front

What is the relationship between the slopes of perpendicular lines?

Back

The slopes of perpendicular lines are negative reciprocals of each other.

Front

If a line has a slope of 0, what does that indicate about the line?

Back

A slope of 0 indicates a horizontal line.
