A.
5x + 7y = 120
-
B.
7x + 5y = 70
-
C.
x + y = 7
-
D.
15x + 17y = 90
Correct Answer: Option B
Explanation
Equation (5, 7) parallel to the line 7x + 5y = 12
5Y = -7x + 12
y = \(\frac{-7x}{5}\) + \(\frac{12}{5}\)
Gradient = \(\frac{-7}{5}\)
∴ Required equation = \(\frac{y - 7}{x - 5}\) = \(\frac{-7}{5}\) i.e. 5y - 35 = -7x + 35
5y + 7x = 70
