Step-by-step explanation:
The given numbers are : 32 , 48 , 140 , 120
First number is 32
Second number is 48
Third number is 140
Fourth number is 120
First number/second number :

Third number/Fouth number :

From equation (1) and (2) we can see that the ratio is not same. Hence, they are not in proportion.
Answer: 3
Step-by-step explanation:
4x-2=10
first you plus 2
10+2=12
4x=12
x=3
Y = mx + c
gradient = -6-9/-8-4
= -15/-12
= 1.2
when x = 4 and y = 9,
9 = 1.2(4) + c
c = 9 - 4.8
= 4.2
The slope of the line is y = 1.2x + 4.2 .
