Slope intercept form of (8, 2); slope -3/4 (y=m*x+b is the formula)

use point slope

y - y1 = m (x - x1)

y - 2 = -3/4 (x - 8)

y - 2 = -3/4x - 24/8

y - 2 = -3/4x - 3

+2                 + 2

     y = -3/4x - 1

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.

happy to

pls mark as brainliest.
