Question
Use the image to answer the question.

An illustration of a coordinate plane with four quadrants shows the x and y axes extending from negative 10 to 10 in increments of 1. A solid line and a dotted line with arrows at both the ends intersect each other. The equation of the solid line is y equals negative x plus 6. The equation of the dotted line is y equals x plus 2. The lines intersect at left parenthesis 2 comma 4 right parenthesis which is not plotted as a point.

Estimate the intersection point of the graphs of the following linear equations in two variables.
y=x+2


y=−x+6


(1 point)
([
],[
])

Answer 1

To find the intersection point of the lines given by the equations \( y = x + 2 \) and \( y = -x + 6 \), we can set the two equations equal to each other because at the intersection point, the y-values will be the same.

1. Set the equations equal:
\[
x + 2 = -x + 6
\]

2. Solve for \( x \):
\[
x + x = 6 - 2
\]
\[
2x = 4
\]
\[
x = 2
\]

3. Substitute \( x \) back into one of the original equations to find \( y \). We'll use \( y = x + 2 \):
\[
y = 2 + 2 = 4
\]

Thus, the intersection point is \((2, 4)\).

In the required format, you can write your answer as:
\[
(2, 4)
\]
