Slope Basics Review

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 of a line given two points (x1, y1) and (x2, y2)?

Back

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

Front

What does a slope of 0 indicate about a line?

Back

The line is horizontal.

Front

What does a positive slope indicate about a line?

Back

As x increases, y also increases.

Front

What does a negative slope indicate about a line?

Back

As x increases, y decreases.

Front

What is the slope of a vertical line?

Back

Undefined.

Front

What is the slope of a horizontal line?

Back

0.

Front

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

Back

For every 1 unit increase in x, y increases by 2 units.

Front

What is the formula to convert from slope-intercept form to standard form?

Back

Ax + By = C, where A, B, and C are integers.

Front

What is the significance of the y-intercept in the slope-intercept form?

Back

It is the point where the line crosses the y-axis.
