Short Answer

What can you say about the slope of (a) the x-axis? And (b) the y-axis?

  1. The slope of xaxis is 0.
  2. The slope o fxaxis is undefined.
See the step by step solution

Step by Step Solution

Part a. Step-1 – Given

The given axis is xaxis.

Step-2 – To determine

We have to find the slope of the xaxis.

Step-3 – Calculation

Slope formula of a line with two points x1,y1  and  x2,y2is:m=y2y1x2x1

Let us take any two points (-1, 0) and (2, 0) on the .

Slope of the line joining these two points, i.e., the slope of xaxis is: m=0021=0

So, the slope of theis 0.

Part b. Step-1 – Given

The given axis is yaxis.

Step-2 – To determine

We have to find the slope of the yaxis.

Step-3 – Calculation

Slope formula of a line with two points x1,y1  and  x2,y2 is

m=y2y1x2x1

Let us take any two points (0, 1) and (0, 3) on the yaxis.

Slope of the line joining these two points, i.e., the slope of is yaxis:

m=3100=20=undefined

So, the slope of the is undefined.
