If the equation y = 1 5 x + 2 is changed to y = 1 5 x - 4, how will the graph of the line change? a) it will shift down 4 units. b) it will shift down 6 units. c) it will shift right 4 units. d) it will shift right 6 units.

ANSWER

B)It will shift down 6 units.

EXPLANATION

The given function is

y=15x+2

We want to find how the graph of this function will change if the function is transformed to

y=15x-4

We rewrite this function in terms of the first one to get:

y=15x+2+-6

Hence the function with shift down 6 units.
