We are given the line 7-4x=7y.
If we write this line in the form y=mx+k, then m is the slope of the line.
7-4x=7y
7y=-4x+7
y=(-4/7)x+1
the slope of the line is -4/7
Any line parallel to this line must also have a slope equal to -4/7.
We want precisely the one passing through (2, 0) and having slope -4/7.
Using the point-slope form of the equation of a line:
(y-0)=-4/7(x-2)
y=(-4/7)x+8/7
Answer: y=(-4/7)x+8/7
another form is 4x+7y-8=0
Is an irrational number because rational numbers are able to be expressed as a quotient of two integers. 22/7 s not an accurate but an approximate expression of pi so it doesn't work. Also, pi is a decimal that goes on without end but doesn't repeat so it is irrational.

Answer: Option 'A' is correct.
Step-by-step explanation:
Since we have given that
Ratio of sapphires to emeralds = 3:1
Let the number of sapphires be 3x.
Let the number of emeralds be 'x'.
According to question, if 6 emeralds are added, we get that
So, Number of sapphires = 3×3 = 9
Number of emeralds = 3
So, total emeralds would be 3+ 6 = 9.
Hence, option 'A' is correct.
