Answer:
y = -2|x| + 1.
Step-by-step explanation:
We start with y = 2x which is a straight line passing through the origin with a slope of 2.
Taking the absolute value of x ( |x| ) gives a graph shaped like a letter V with the point at the origin.
Making that negative ( y = -2|x| ) inverts it vertically and then the + 1 translates it up 1 unit.
