Answer: a = -3

==================================================

Work Shown:

The point (1, -3) is on the blue graph p(x) = a|x|

This means x = 1 and y = -3 pair up.

Use these two values to find 'a'

p(x) = a|x|

y = a|x|

-3 = a*|1|

-3 = a*1

-3 = a

a = -3

The negative 'a' value will apply the reflection over the x axis. The fact that |a| = 3 is larger than 1 indicates the graph is vertically stretched by a factor of 3.
