Front

What does the x-intercept represent in a function?

Back

The x-intercept represents the value of x when the function's output is zero.

Front

What is the formula for calculating slope between two points (x1, y1) and (x2, y2)?

Back

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

Front

What does a slope of 0 indicate about a line?

Back

A slope of 0 indicates a horizontal line.

Front

Back

The y-intercept is the value of y when x = 0.

Front

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

Back

Subtract the y-coordinates and divide by the difference of the x-coordinates.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that the line is decreasing.
