Question

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 \( y = 1 \).
