Slope and Y-Intercept

Front

What is the y-intercept?

Back

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

Front

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

Back

'm' represents the slope of the line.

Front

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

Back

'b' represents the y-intercept of the line.

Front

How do you find the slope of a line?

Back

The slope is found by taking the difference in y-values divided by the difference in x-values between two points on the line.

Front

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

Back

The slope is 2.

Front

What is the formula for slope?

Back

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

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 y-intercept of the line y = 5?

Back

The y-intercept is 5.

Front

What is the slope of the line y = 2x + 1?

Back

The slope is 2.
