Lessons 4.1-4.3, 4.6 Review

Front

What is the slope of a vertical line?

Back

Undefined

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

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

Back

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

Front

What does a slope of 0 indicate about a line?

Back

The line is horizontal.

Front

What is an arithmetic sequence?

Back

A sequence of numbers in which the difference between consecutive terms is constant.

Front

How do you find the nth term of an arithmetic sequence?

Back

a_n = a_1 + (n-1)d, where a_1 is the first term and d is the common difference.

Front

What is the common difference in the sequence 5, 12, 19, 26...?

Back

The common difference is 7.

Front

Convert the equation y + 5 = -3(x - 6) to slope-intercept form.

Back

y = -3x + 13

Front

What is the y-intercept in the equation y = 3x + 6?

Back

The y-intercept is 6.

Front

If m = 3 and b = 6, what is the slope-intercept equation?

Back

y = 3x + 6
