Flashcard 13

Front

What is the equation of a line with a slope of 5 and a y-intercept of 5?

Back

y = 5x + 5

Front

What is a common difference in a sequence?

Back

The common difference is the amount added to each term to get to the next term in an arithmetic sequence.

Front

Identify the equation of a line with a slope of 4 and a y-intercept of -32.

Back

y = 4x - 32

Front

What point represents the y-intercept on a graph?

Back

(0, b) where b is the y-intercept value.

Front

How do you reflect a point across the line y=x?

Back

Swap the x and y coordinates of the point.

Front

What is the formula for the slope of a line?

Back

Slope (m) = (y2 - y1) / (x2 - x1) for two points (x1, y1) and (x2, y2).

Front

What is an arithmetic sequence?

Back

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

Front

What does the y-intercept represent in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis.

Front

How do you find the slope from a graph?

Back

Choose two points on the line, calculate the rise over run (change in y over change in x).

Front

What is the general form of a linear equation?

Back

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