Slope and Y-intercept

Front

What is the slope of a line?

Back

The slope of a line is a number that describes how steep the line is. It is calculated as the rise (change in y) over the run (change in x).

Front

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

Back

In the equation y = mx + b, 'm' represents the slope of the line.

Front

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

Back

In the equation y = mx + b, 'b' represents the y-intercept of the line.

Front

How do you find the y-intercept of a line?

Back

To find the y-intercept, set x to 0 in the equation of the line and solve for y.

Front

What is the y-intercept of the equation y = 3x + 4?

Back

The y-intercept is 4.

Front

What is the slope of the line that passes through the points (1, 2) and (3, 6)?

Back

The slope is 2.

Front

If a line has a slope of 0, what does that mean?

Back

A slope of 0 means the line is horizontal.

Front

If a line has an undefined slope, what does that mean?

Back

An undefined slope means the line is vertical.

Front

What is the slope of the line that passes through the points (2, 3) and (2, 5)?

Back

The slope is undefined.

Front

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

Back
