Front

What is the value of x² - xy if x = 8 and y = -3?

Back

88

Front

Which equation matches the table? y = 3x + 9, y = 1/3x + 9, y = x + 3, y = 12x - 3

Back

y = 3x + 9

Front

Find the slope of the line that passes through the points (2, 4) and (6, 12).

Back

2

Front

Is the relation defined by the set of points a function?

Back

Function

Front

What do the lines -6x + y = 2 and 6x + y = 2 represent?

Back

Neither

Front

What is the definition of a function?

Back

A relation where each input has exactly one output.

Front

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

Back

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

Front

What is the standard form of a linear equation?

Back

Ax + By = C, where A, B, and C are integers.

Front

What does it mean for two lines to be parallel?

Back

They have the same slope and will never intersect.

Front

What does it mean for two lines to be perpendicular?

Back

Their slopes are negative reciprocals of each other.
