Understanding Y-Intercept and Slope

What is the definition of y-intercept?

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

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

• The y-intercept is the slope of a line.

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

What is the definition of slope?

• The slope is the ratio of the horizontal change to the vertical change between two points on a line.

• The slope is the y-intercept of a line.

• The slope is the distance between two points on a line.

• The slope is the ratio of the vertical change to the horizontal change between two points on a line.

How can you graphically interpret the slope?

• The slope represents the y-intercept of a graph.

• The slope represents the area under the curve of a graph.

• The slope represents the maximum value of a graph.

• The slope represents the rate of change between two points on a graph.

How can you interpret the slope and y-intercept from a word problem?

• The slope represents the initial value and the y-intercept represents the rate of change.

• The slope represents the maximum value and the y-intercept represents the minimum value.

• The slope represents the rate of change and the y-intercept represents the initial value or starting point.

• The slope represents the final value and the y-intercept represents the average value.

In a linear equation, if the y-intercept is 3, what does it mean?

• The y-intercept of 3 means that the line crosses the y-axis at the point (0, 3).

• The y-intercept of 3 means that the line is vertical.

• The y-intercept of 3 means that the line is horizontal.

• The y-intercept of 3 means that the line crosses the x-axis at the point (3, 0).

In a linear equation, if the slope is 2, what does it mean?

• The slope of 2 means that the line is vertical.

• The slope of 2 means that the line is horizontal.

• The slope of 2 means that the line is decreasing at a rate of 2 units for every 1 unit increase in the x-coordinate.

• The slope of 2 means that the line is increasing at a rate of 2 units for every 1 unit increase in the x-coordinate.

If the y-intercept of a line is zero, what does it mean?

• The line is vertical.

• The line is parallel to the x-axis.

• The line is horizontal.

• The line passes through the origin.
