Question

If y = 4x + 3 were changed to y = -4x + 3, how would the graph of the new function compare with the original?

Answer 1

4x+3 times -1 reflects the graph about the x axis

-4x-3 adding 6 moves the graph upwards by 6 units

-4x-3+6

-4x+3

Answer 2

The graph of y=-4x+3 will be as a reflexion in a mirror of y=4x+3

Explanation:

y=4x+3 y=-4x+3
