Please help me, I will give brainliest, I am struggling badly.

Slope Number 1 is Harry.

Step-by-step explanation:

y = -1/2 + 30

-1 being one less exercise to complete

2 being the 2 minutes spent on each exercise

and 30 being the number of exercises

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
