# Answer to Question #33149 in Geometry for Tevin Young

Question #33149

What is the common point between lines y = ½ x + 4 and y = x – 4?

Expert's answer

Common point belongs to both given lines. To find it we should equate given expressions for y:

1/2 x+4=x-4

1/2x=8

x=16

Now we need to find corresponding y. We can use either of the given equations for that:

y(16)=16-4=12

Thus, we found common point of the given lines, it's (16,12)

1/2 x+4=x-4

1/2x=8

x=16

Now we need to find corresponding y. We can use either of the given equations for that:

y(16)=16-4=12

Thus, we found common point of the given lines, it's (16,12)
