To solve for the value of \( y \) in the equation \( y = -2x + 5 \) when \( x = 2 \), substitute \( 2 \) for \( x \):
\[ y = -2(2) + 5 \]
Now calculate:
\[ y = -4 + 5 \]
\[ y = 1 \]
So, when \( x = 2 \), the value of \( y \) is \( 1 \).
You’re trying to find the value of y when x=2. You can use either equation to find the value of y. Start with y=−2x+5. Substitute 2 for x in this equation.
y=−2x+5
y=4x−7
