Then multiply 5 12ths by  10. 5/12 *10=50/120. So, 7/10 > 5/12

What is the slope of the line that passes through the points ( −8,−1) and (-12,-2)
omeli [17]

Answer:

1/4

Step-by-step explanation:

We can find the slope of a line given two points from the formula

m = (y2-y1)/(x2-x1)

   = (-2--1)/(-12--8)

   = (-2+1)/(-12+8)

    =-1/-4

   = 1/4
