Hi, 
*Note: one may 'graph' the line by plotting the points and drawing the line thru them
Knowing that the x values increase by 9 as the y values decrease by 4
this discovery has led to the 'slope' of the line is (-4/9) 
Note: the general slope-intecept form of an equation of a line is:
y = mx + b  where m is the slope and b is the y value where the line crosses the y-axis
If you were looking for an equation of the line:
y = (-4/9)x + b
subsituting one of the ordered pairs to solve for b
(1,6)
6 = (-4/9)*1 + b
6 + 4/9) = b
58/9= b
y = (-4/9)x + 58/9  would be the equation of the line, 
which could also be written in standard form by mulitplying each side of the equation by 9
4x + 9y = 58
