Question

If y = $\frac{1}{2}$ (3x+7) is rewritten in the form ax + by + c = 0, what are the values of a, b and c?

• A. -3, 2, -7
• B. -2, 3, -7
• C. 7, 2, 3
• D. $\frac{1}{2}$ , $\frac{7}{2}$ , $\frac{3}{2}$

Answer 1

The correct option is A -3, 2, -7

The given equation is: y = $\frac{1}{2}$ (3x+7)
Simplyfying the equation we get:
2y = 3x + 7
-3x + 2y -7 = 0 (1)
On comparing the equation 1 with ax + by + c = 0, the values of a, b and c are -3, 2 and -7 respectively.
