Front

What are the slopes of perpendicular lines?

Back

Slopes of perpendicular lines are opposite reciprocals.

Front

What is the slope of a line perpendicular to 5?

Back

The slope of a line perpendicular to 5 is -1/5.

Front

Write the equation of the line with a slope of -3 and a y-intercept of -3.

Back

y = -3x - 3

Front

What equation represents the total cost of a holiday meal for x people, where each person costs $12.50 and there is a $30 delivery fee?

Back

y = 12.5x + 30

Front

What does 'b' represent in the slope-intercept equation (y = mx + b)?

Back

b = the y-intercept.

Front

If the slope of a line is 2, what is the slope of a line perpendicular to it?

Back

The slope of a line perpendicular to it is -1/2.

Front

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

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 (m) is calculated as m = (y2 - y1) / (x2 - x1).

Front

What is the y-intercept of the line represented by the equation y = 4x + 5?

Back

The y-intercept is 5.

Front

If a line has a slope of 0, what type of line is it?

Back

A line with a slope of 0 is a horizontal line.
