Question

for the two variable equation y=-2x-1 find the matching y value when x=1.

Answer 1

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

\[
y = -2(1) - 1
\]

Now perform the calculation:

\[
y = -2 - 1 = -3
\]

Thus, when \( x = 1 \), the matching \( y \) value is \( -3 \).
