Question

What is the slope of the line that passes through the points (4, 9) and (1, 6)?

Answer 1

a = ( 1 , 6 )

b = ( 4 , 9 )

`slope = (y(b) - y(a))/(x(b) - x(a)) \\`

Now just need to put the coordinates in the above equation :

`slope = (9 - 6)/(4 - 1) \\`

`slope = (3)/(3) \\`

`slope = 1`

And we're done...♥️♥️♥️♥️♥️
