Question 1

What is the slope of a horizontal line?

Accepted Answer

The slope of a horizontal line is 0 because there is no change in the y-values as x-values change.

Question 2

What is the slope of a vertical line?

Accepted Answer

The slope of a vertical line is undefined because the change in x-values is 0, which would require division by zero in the slope formula.

Question 3

Can the slope be a negative number?

Accepted Answer

Yes, a negative slope indicates that the line is decreasing, meaning it goes down from left to right.

Question 4

What do parallel lines have in common regarding slope?

Accepted Answer

Parallel lines have the same slope.

Question 5

How does the slope formula relate to a linear equation?

Accepted Answer

In a linear equation of the form y = mx + b, 'm' represents the slope of the line.
