Front

What is the y-intercept of the line: y = -2x + 6?

Back

The y-intercept is 6.

Front

What is the general form of the slope-intercept equation?

Back

The general form is y = mx + b.

Front

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

Back

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

Front

If a line has a slope of 0, what does that indicate about the line?

Back

A slope of 0 indicates a horizontal line.

Front

If a line has an undefined slope, what does that indicate about the line?

Back

An undefined slope indicates a vertical line.

Front

What does the b represent in the equation y=mx+b?

Back
