Question 947739
 Find the slope of the line that goes through the points (-2,15) and (-1,-12)
 enter the answer as an integer or a reduced fraction in the form a/b
:
The slope formula: m = {{{((y2-y1))/((x2-x1))}}}
in this problem:
x1 =-2; y1 = 15
x2 =-1; y2 =-12
:
m = {{{((-12-15))/((-1-(-2)))}}}
minus a minus is a plus
m = {{{((-12-15))/((-1+2))}}} = {{{(-27)/1}}}
m = -27 is the slope
