Question
What value for b
would make this equation proportional?
y=3x+b
(1 point)

Answer 1

For the equation \( y = 3x + b \) to be proportional, it must pass through the origin (0, 0). This means that when \( x = 0 \), \( y \) should also be equal to 0.

Substituting \( x = 0 \) into the equation:

\[ y = 3(0) + b \implies y = b \]

For the equation to be proportional, we set \( y \) to 0:

\[ 0 = b \]

Thus, the value of \( b \) that would make the equation proportional is:

\[ \boxed{0} \]
