y = –x + 4

y = 2x − 2

1 answer

To find the intersection of the two lines given by the equations \( y = -x + 4 \) and \( y = 2x - 2 \), we can set the two equations equal to each other:

\[ -x + 4 = 2x - 2 \]

Now, we'll solve for \( x \):

  1. Add \( x \) to both sides:

\[ 4 = 3x - 2 \]

  1. Add \( 2 \) to both sides:

\[ 6 = 3x \]

  1. Divide by \( 3 \):

\[ x = 2 \]

Now that we have \( x \), we can substitute it back into either of the original equations to find \( y \). We'll use the first equation:

\[ y = -x + 4 = -2 + 4 = 2 \]

So, the intersection point of the two lines is:

\[ (x, y) = (2, 2) \]

Thus, the solution is \( (2, 2) \).
