Lesson: Slope and Y-intercept from a graph

Front

What does the 'b' in y = mx + b stand for?

Back

y-intercept

Front

What is the formula to find the slope of a line?

Back

Slope (m) = rise/run

Front

What type of slope does a line with a positive slope have?

Back

Positive slope means the line rises from left to right.

Front

What type of slope does a line with a negative slope have?

Back

Negative slope means the line falls from left to right.

Front

What does a slope of zero indicate about a line?

Back

A slope of zero indicates a horizontal line.

Front

What does an undefined slope indicate about a line?

Back

An undefined slope indicates a vertical line.

Front

How do you determine the y-intercept from a graph?

Back

The y-intercept is where the line crosses the y-axis.

Front

If a line crosses the y-axis at (0, -1), what is the y-intercept?

Back

b = -1

Back

For every 2 units you move right, the line rises 3 units.
