SOLUTION: Find the value of k if the line x-y=2k has the same x-intercept as y=4x-8

Question 472334: Find the value of k if the line x-y=2k has the same x-intercept as y=4x-8
Answer by MathLover1(20850) (Show Source): You can put this solution on YOUR website!
an x-intercept is a point on the graph where y is zero
......1
......2....if y is zero
----------------------------------------
........1
........2....solve for
----------------------------------------------
........2

.....plug it in 1
........1....solve for

so the line is ...->.. or in form

let's see it on a graph:

from the graph you can see that both lines have sam at point (,)
