Answer: option A. y = 6x

If you draw both  lines, you will see that the new one, y = 6x, looks like the original line y = x, was streched up-down.

That is because for the same value of x, for the new line, y = 6x, the value of y-coordinated is higher if x is positive or lower if x is negative than for the  original line y =x.

For this case we have the following linear equation:
 [tex]y = x [/tex]
 We apply the following function transformation:
 Vertical expansions:
 To graph y = a * f (x)
 If a> 1, the graph of y = f (x) is expanded vertically by a factor a.
 For this case we have:
 [tex]y = 6 * f (x) [/tex]
 Substituting values:
 [tex]y = 6x [/tex]
 Answer:
 an equation for the transformation is:
 A. y = 6x
