Question

The end points of a line are (2, 3), (4, 5). Find the slope of the line.

Answer 1

Hi ,

Let A ( x1 , y1 ) = ( 2 , 3 )

and

B( x2 , y2 ) = ( 4 , 5 )

Slope of a line AB = ( y2 - y1 )/( x2 - x1 )

m = ( 5 - 3 )/( 4 - 2 )

m = 2/2

m = 1

Therefore ,

Required slope ( m ) = 1

I hope this helps you.

Answer 2

slope=(y2-y1)/(x2-x1)

  =(5-3)/(4-2)

slope=1

angle of inclination   tan theta=slope

tan theta=1

hence theta=45
