Linear Part of review for FLASHCARD FRIDAY

Front

What is the slope of a line that is perpendicular to a line with slope m = 5/8?

Back

-8/5

Front

What is the slope of the line represented by the equation 3x - 5y = 7?

Back

3/5

Front

Are the lines y = 6x + 2 and y = -6x + 2 parallel, perpendicular, or neither?

Back

Neither

Front

Write the equation of the line that passes through the points (2,6) and (3,1).

Back

y = -5x + 16

Front

Are the lines y = -2/3x + 2 and y = 3/2x + 9 parallel, perpendicular, or neither?

Back

Perpendicular

Front

What is the definition of slope?

Back

Slope is the measure of the steepness of a line, calculated as the rise over run.

Front

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

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

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

Back

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

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope and 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.
