Question

the __________ plane is a two-dimensional plane formed by the intersection of a vertical y-axis and a horizontal x-axis.

the __________ of a line tells us how steep that line is.

a __________ slope means that the line rises as x increases.

a __________ slope means that the line falls as x increases.

the __________ value is the independent variable in a function, often representing the input or horizontal position in a table or graph.

Explanation:

These are key terms from coordinate geometry and linear functions.

1. The plane formed by x and y axes is the Cartesian plane.
2. The measure of a line's steepness is its slope.
3. A line that rises as x increases has a positive slope.
4. A line that falls as x increases has a negative slope.
5. The independent input variable for horizontal position is the x-value.

Answer:

1. Cartesian
2. slope
3. positive
4. negative
5. x-
