What does a solid line indicate in a graph?

Back

A solid line indicates that the points on the line are included in the solution set.

Front

What does a dotted line indicate in a graph?

Back

A dotted line indicates that the points on the line are not included in the solution set.

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 is the slope of the line that passes through the points (2, 3) and (3, 5)?

Back

The slope is 2.

Front

What is the y-intercept of a line?

Back

The y-intercept is the point where the line crosses the y-axis.

Front

What is the y-intercept of the line represented by the equation y = 2x - 4?

Back

The y-intercept is -4.

Front

What is the range of a function?

Back

The range is the set of all possible output values (y-values) of a function.

Front

What is the range of the graph if it is defined as -3 ≤ y < 1?

Back

The range includes all y-values from -3 to just below 1.

Front

What value of x satisfies the equation 5x = 1?

Back

Front

What is the solution to the equation 2x + 3 = 7?

Back
