Back

The common difference is 4.

Front

Convert the standard form equation 5x + y = -5 into slope-intercept form.

Back

The slope-intercept form is y = -5x - 5.

Front

What type of line is represented by the equation y = -5?

Back

The line is horizontal.

Front

What is the equation of the vertical line that passes through x = -2?

Back

The equation is x = -2.

Front

What is the definition of a common difference in a sequence?

Back

Front

What is slope-intercept form?

Back

Slope-intercept form is an equation of the line written as y = mx + b, where m is the slope and b is the y-intercept.

Front

What does a horizontal line represent in a graph?

Back

A horizontal line represents a constant value of y, regardless of the value of x.

Front

What is the difference between a vertical line and a horizontal line?

Back

A vertical line has an undefined slope and represents x = constant, while a horizontal line has a slope of 0 and represents y = constant.

Front

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

Back

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