Slope Sum

Front

The slope of a line is defined as _____?

Back

The ratio of the change in the y-coordinate to the change in the x-coordinate between two points on the line.

Front

What is the slope-intercept form of a linear equation?

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you find the slope from two points (x1, y1) and (x2, y2)?

Back

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

Front

What does a positive slope indicate about a line?

Back

The line rises from left to right.

Front

What does a negative slope indicate about a line?

Back

The line falls from left to right.

Front

What is the slope of a vertical line?

Back

Undefined.

Front

What is the slope of a horizontal line?

Back

Zero.

Front

In the equation y = mx + b, what does 'm' represent?

Back

The slope of the line.

Front

If the slope of a line is 3/7, what does this mean?

Back

For every 7 units moved horizontally, the line moves up 3 units vertically.

Front

Convert the equation 3x - 6y = 12 to slope-intercept form.

Back

y = 1/2x - 2.
