Front

What is the slope of a horizontal line?

Back

0

Front

What is the point-slope form of a line?

Back

y - y1 = m(x - x1)

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 an undefined slope indicate?

Back

A vertical line.

1/2

Front

What does the 'm' represent in the slope-intercept form y=mx+b?

Back

The slope of the line.

Front

What does the 'b' represent in the slope-intercept form y=mx+b?

Back

The y-intercept of the line.

Front

If a line has a slope of -1, what does that indicate about its direction?

Back

The line descends from left to right.
