Line one y=-2x+8

Line to y=4x-10

Review the graphs of a system of these two linear equations in two variables: y=4x-10 and y=-2x+8 Find the solution of the system.

1 answer

To find the solution of the system of equations given by:

  1. \( y = -2x + 8 \)
  2. \( y = 4x - 10 \)

we need to find the point \((x, y)\) where these two lines intersect. This means we can set the two equations equal to each other since both are equal to \(y\):

\[ -2x + 8 = 4x - 10 \]

Now, let's solve for \(x\):

  1. Add \(2x\) to both sides: \[ 8 = 6x - 10 \]

  2. Add \(10\) to both sides: \[ 18 = 6x \]

  3. Divide by \(6\): \[ x = 3 \]

Next, we can substitute \(x = 3\) back into either of the original equations to find \(y\). We'll use the first equation:

\[ y = -2(3) + 8 \] \[ y = -6 + 8 \] \[ y = 2 \]

So, the solution to the system of equations is:

\[ (x, y) = (3, 2) \]

Thus, the lines intersect at the point \((3, 2)\).
