Back

5

Front

Which ordered pair is in the solution set of the following system of inequalities? y < \frac{1}{2}x + 4 and y \ge -x + 1

Back

(4, 0)

Front

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

Back

y-intercept

Front

What is the slope of the line passing through points A and B if the slope is calculated as \frac{y_2 - y_1}{x_2 - x_1}?

Back

\frac{1}{2}

Front

What is the general 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) = \frac{y_2 - y_1}{x_2 - x_1}

Front

What is the meaning of a positive slope in a linear equation?

Back

A positive slope indicates that as x increases, y also increases.

Front

What is the meaning of a negative slope in a linear equation?

Back

A negative slope indicates that as x increases, y decreases.

Front

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

Back

2

Front

What does it mean for a line to be parallel to another line?

Back

Two lines are parallel if they have the same slope.
