Finding Slope

Front

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

Back

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

Front

What does a slope of 0 indicate about a line?

Back

A slope of 0 indicates that the line is horizontal.

Front

What does an undefined slope indicate about a line?

Back

An undefined slope indicates that the line is vertical.

Front

How do you determine if the slope is positive or negative?

Back

If the line rises from left to right, the slope is positive. If it falls from left to right, the slope is negative.

Front

What is the slope of the line represented by the equation y = 2x + 3?

Back
