Front

If a liquid cools at a constant rate of 60F every minute, what is the rate of change?

Back

-60F per minute.

Front

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

Back

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

Front

What is the equation of a line with a slope of 4 and a y-intercept of 6?

Back

y = 4x + 6.

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 convert from standard form to slope-intercept form?

Back

Solve for y to get y = mx + b.

Front

What is the slope of the line represented by the equation y = -2x + 3?

Back
