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 )

$slope = \frac{y(b) - y(a)}{x(b) - x(a)}$

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

$slope = \frac{9 - 6}{4 - 1}$

$slope = \frac{3}{3}$

$slope = 1$

And we're done...♥️♥️♥️♥️♥️
