Graphing Linear Equations

Front

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

Back

y = mx + b

Front

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

Back

slope = (y2 - y1) / (x2 - x1)

Front

What is the equation of a horizontal line?

Back

y = c

Front

What is the equation of a vertical line?

Back

x = c

Front

When are two lines considered parallel?

Back

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

Front

When are two lines considered perpendicular?

Back

Two lines are considered perpendicular when the angle between them is 90 degrees.

Front

What is the slope-intercept form of the equation of a line parallel to y = 2x + 3?

Back

y = 2x + b

Front

What is the slope-intercept form of the equation of a line perpendicular to y = -3x + 4?

Back

y = (1/3)x + b
