Using the rule y = 3x + 4, find the value of y when x is 2.

A) 9

B) 10

C) 11

D) 12

Equation:y=3x+4. Given x=2

y=3 (2) + 4

y=6+4

y=10

Answer is B.

The answer is 10.

Here's why:

The equation that we have is y=3x+4, we know the value of x, but not the value of y.

If x=2, the new equation is:

y=3 (2) + 4

3 (2) = 6 + 4=10

The answer is 10 which means that B is correct.
