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. , ,

Answer 1

The correct option is A

-3,2,-7

The given equation is:

$y=\frac{1}{2}(3x+7)$

Simplifying the equation we get:

$2y-3x-7=0$

$\Rightarrow -3x+2y-7=0$ (1)

Thus, the value of a, b and c is -3, 2 and -7 respectively.

The equation can also be written as,

$3x-2y+7=0$

Thus, the value of a, b and c is +3, -2 and +7 respectively.

The option -3, 2 and -7 is correct [Since +3, -2 and +7 is not an option]
