What is the distributive property?

Back

The distributive property states that a(b + c) = ab + ac. It allows you to multiply a single term by two or more terms inside a set of parentheses.

Front

Use the distributive property to simplify: 2(8r + 2s - 1)

Back

16r + 4s - 2

What is 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

Write the equation of the line in slope-intercept form: y = (5/2)x - 5

Back

y = \frac{5}{2}x - 5

What is an explicit formula for a sequence?

Back

An explicit formula defines the nth term of a sequence as a function of n.

Front

Write an explicit formula for the sequence 32, 42, 52, ...

Back

a_n = 32 + 10(n - 1)

Front

How can you determine if two lines are parallel?

Back

Two lines are parallel if they have the same slope.

Front

Are the lines y = (-1/2)x + 1 and y = (1/2)x - 5 parallel?

Back

NO

Use the distributive property to simplify: 10(h - 9k + 7)

Back

10h - 90k + 70

What is the formula for the slope of a line?

Back

The slope (m) is calculated as m = (y2 - y1) / (x2 - x1).
