Front

What does the equation D = 72 - 59t represent?

Back

The distance D from Athens to Atlanta after t hours, where 59 is the speed of the car.

Front

What does the number 59 represent in the equation D = 72 - 59t?

Back

The speed of the car.

Front

What are the x- and y-intercepts of a graph?

Back

The points where the graph crosses the x-axis and y-axis, respectively.

Front

What does 'm' represent in the equation y = mx + b?

Back

The slope of the line.

Front

How do you find the y-intercept of a linear equation?

Back

Set x = 0 and solve for y.

Front

What is the y-intercept of the equation 2x - 5y = 35?

Back

(0, -7).

Front

How do you calculate the slope of a line?

Back

Slope (m) = (change in y) / (change in x).

Front

What is the slope of the line represented by the equation y = (1/3)x + 2?

Back

1/3.

Front

What is the standard form of a linear equation?

Back

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

Front

What is the difference between x-intercept and y-intercept?

Back

X-intercept is where the graph crosses the x-axis (y=0), and y-intercept is where it crosses the y-axis (x=0).
