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 (x1, y1) and (x2, y2)?

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

How do you determine if two lines represented by equations are parallel, perpendicular, or neither?

Back

Convert both equations to slope-intercept form (y = mx + b) and compare their slopes.

Front

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

Back

The midpoint M is given by M = ((x1 + x2)/2, (y1 + y2)/2).

Front

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

Back

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

Front

What is the equation of a line that passes through the point (2,5) and has a slope of 2?

Back

The equation is y = 2x + 1.

Front

How do you convert the standard form of a line, Ax + By = C, to slope-intercept form?

Back

Solve for y to get y = (-A/B)x + (C/B).

Front

What is the y-intercept of the line represented by the equation y = 3x + 4?

Back

The y-intercept is 4.
