for the two variable equation y=2x+1, find the matching y value when x=-3

Answer 1

To find the value of \( y \) when \( x = -3 \) in the equation \( y = 2x + 1 \), substitute \(-3\) for \( x \):

\[ y = 2(-3) + 1 \] \[ y = -6 + 1 \] \[ y = -5 \]

So, when \( x = -3 \), the matching \( y \) value is \(-5\).
