Slope formula : (y2 - y1) / (x2 - x1)
set 1 : (12,7)....x1 = 12 and y1 = 7
set 2 : (9,6)....x2 = 9 and y2 = 6
now we sub
slope = (6 - 7) / (9 - 12) = -1/-3 = 1/3 <==

4000ml /1000 = 4 l
Answer:
The 2 numbers are 158 & 199
Step-by-step explanation:
Let 1st no. = x
2nd no. = y
x + y = 357 -----(1)
x - y = 41 ------(2)
(1)-(2)
2y = 316
y = 158
suby=158into(1)
x + 158 = 357
x = 199
