Short Answer

Expert verified

Sometime the slope of a line is real number

Step by step solution

01

Step-1 –Determining the slope of line

Slope, m=y2-y1x2-x1

Where (x1,y1) and (x2,y2) are points on the line.

02

Step-2 –Showing slope of a line is real number 

Let us consider a line whose equation is y=2x+3 having slope = 2 which is a real number

03

Step-3 –Showing slope of line is not real number

If a line is a vertical line, the slope is undefined.

So, sometimes the slope of a line is real number.
