Q. 6 - Geometry

Question

Does the slope of the line appear to be positive, negative, zero, or not defined?

Step-by-Step Solution

Answer

1. The given line has positive slope.
2. The given line has undefined slope.
3. The given line has negative slope.

      4.   The given line has slope zero.

Part a. Step-1 – Given

The given figure is:

Step-2 – To determine

We have to find whether the slope of line appear to be positive, negative, zero or not defined.

Step-3 – Calculation

From given figure we see that the line is increasing as it goes from left to right.

So, the given line has a positive slope.

Part b. Step-1 – Given

The given figure is:

Step-2 – To determine

We have to find whether the slope of line appear to be positive, negative, zero or not defined.

Step-3 – Calculation

From given figure we see that the line is vertical.

So, the given line has undefined slope.

Part c. Step-1 – Given

The given figure is:

Step-2 – To determine

We have to find whether the slope of line appear to be positive, negative, zero or not defined.

Step-3 – Calculation

From given figure we see that the line is decreasing as it goes from left to right.

So, the given line has a negative slope.

Part d. Step-1 – Given

The given figure is:

Step-2 – To determine

We have to find whether the slope of line appear to be positive, negative, zero or not defined.

Step-3 – Calculation

From given figure we see that the line is horizontal.

So, the given line has slope zero.
