for the two variable equation y=3x+4, find the matching y value when x=-1

Answer 1

To find the matching \( y \) value for the equation \( y = 3x + 4 \) when \( x = -1 \), substitute \(-1\) into the equation:

\[ y = 3(-1) + 4 \]

Now, calculate:

\[ y = -3 + 4 = 1 \]

So, when \( x = -1 \), the matching \( y \) value is \( y = 1 \).
