Front

What is the formula for slope (m) between two points (x1, y1) and (x2, y2)?

Back

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-intercept form of a linear equation?

Back

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

Front

What is the standard form of a linear equation?

Back

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

Front

How do you find the y-intercept from the slope-intercept form?

Back

Set x = 0 and solve for y.

Front

If a line has a slope of -3, what does this mean?

Back

For every 1 unit increase in x, y decreases by 3 units.
