A) 8 - add up the how many numbers there are after the 4 on the left column
b) 41 - line up all of the numbers from least to greatest and find the middle number
c) 39 - do step b again but this time remove the oldest worker and add the younger one in
Step-by-step explanation:
given
3x + y = 9
Writing In slope intercept form , y = mx + c
y = -3x + 9
comparing the given equation with y = mx + c
slope (m) = - 3
y-intercept (c) = 9
Hope it will help :)
