hartnn · Answer

The slope of the line through points (x1,y1) and (x2,y2) is given by :
$\huge m=\frac{y_1-y_2}{x_1-x_2}$
now,just put the values and find m.

Or, plot them on a graph paper , 
Extend the line till it cuts the X axis somewhere
Using protractor or any other legit method, Find the angle the line makes with the positive X axis (the right side angle) .
The tan of that angle = slope of the line !
;)

@hartnn  a single line space between lines would make it look better :P  .....@alexus_19  use the formula above to get slope :)

um like im doing a online test for credit recovery from when i was in the 9th grade so we dont get to use graph paper or a protractor, so is there any way to figure it out in some type of solution ? :]

hartnn · Answer

just plug in points in the formula
x1=9, x2=3
y1=3, y2=-6
and you'll get slope =m.
