What is the common difference in the arithmetic sequence: -34, -29, -24, -19, ...?

Back

d = 5

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

What is the slope of the line represented by the equation y = -2/3x + 2?

Back

The slope is -2/3.

Front

What is the slope of the line represented by the equation y = 3/2x + 9?

Front

How do you find the 35th term in an arithmetic sequence?

Back

Use the formula: a_n = a_1 + (n-1)d.

Front

What is the explicit rule for the arithmetic sequence: -10, -14, -18, -22, ...?

Back

The explicit rule is a_n = -10 + (n-1)(-4).

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 determine if two lines are parallel?

Back

Two lines are parallel if they have the same slope.

Front

What is the formula to calculate the nth term of an arithmetic sequence?

Back

The formula is a_n = a_1 + (n-1)d.
