What is the slope of the line that passes through the pair of points (-5/3,-1) and (-2,9/2)?

The slope of te line that passes throug (x1,y1) and (x2,y2) is
(y2-y1)/(x2-x1)
given
(-5/3,-1) and (-2,9/2)
slope=(9/2-(-1))/(-2-(-5/3))=
(9/2+2/2)/(-6/3+5/3)=
(11/2)/(-1/3)=
(11/2)(-3/1)=
-33/2
the slope is -33/2
