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 change in y divided by the change in x.

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, which is the point where the line crosses the y-axis.

Front

How do you find the slope from a table of values?

Back

To find the slope from a table, use the formula (change in y) / (change in x) between two points.

Front

What type of slope is represented by a line that goes up from left to right?

Back

Positive slope.

Front

What type of slope is represented by a line that goes down from left to right?

Back

Negative slope.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

If a line has a slope of -1, what does that mean?

Back

It means that for every 1 unit you move to the right, you move down 1 unit.

Front

If a line has a slope of 2, what does that mean?

Back

It means that for every 1 unit you move to the right, you move up 2 units.
