Answer:
from sloping up to sloping down ⇒ answer D
Explanation:
* Lets talk about the transformation
- If the function f(x) reflected across the x-axis, then the new
function g(x) = - f(x)
- If the function f(x) reflected across the y-axis, then the new
function g(x) = f(-x)
* Now lets solve the problem
∵ The equation of the line is y = 2x - 6
∵ The equation is changed to y = -2x - 6
- If the both signs of x and the number are changed means the
equation is multiplied by -1
∴ The line is reflected across the x-axis
- If the sign of x only is changed
∴ The line is reflected across the y-axis
- From the equation 2x changed to -2x, but -6 not changed
∴ The sign of x only changed
∴ The line is reflected across the y-axis
* The graph is reflected across the y-axis
∴ from sloping up to sloping down
