Line ab goes through points a(3, 4) and b(7, 7).

The equation of line is 4 y - 3 x - 7 = 0

Step-by-step explanation:

Given points of line as

A = ( 3 , 4 )

B = ( 7 , 7 )

Now The equation of line is written as :

Where m is the slope of line

So, m =

Or, m =

Or, m =

∴ slope of line is    

Now equation of line with slope and points as

Or, 4× ( y - 4 ) = 3× ( x - 3 )

Or, 4 y - 16 = 3 x - 9

Or, 4 y - 3 x - 7 = 0

Hence The equation of line is 4 y - 3 x - 7 = 0   Answer

answer: 140
