They don't have to point in the same direction.
They don't have to be on similar sized lines.
Just the same angle.
Hope this helped!

Answer: Choice C</h3>
=============================================
Explanation:
Choices A, B and D are not true because of the negative y values. The result of an absolute value is never negative. So we can rule out choices A, B, and D. We have choice C as the only thing left, so this must be the answer.
-------------
Another way to see this is by plugging in each x value to see what y value comes out.
- If x = -2, then y = |5*x| = |5*(-2)| = |-10| = 10
- If x = -1, then y = |5*x| = |5*(-1)| = |-5| = 5
- If x = 0, then y = |5*x| = |5*0| = |0| = 0
- If x = 1, then y = |5*x| = |5*1| = |5| = 5
- If x = 2, then y = |5*x| = |5*2| = |10| = 10
The y outputs from top to bottom are: 10, 5, 0, 5, 10
This matches with what choice C shows.
Answer:
D
Step-by-step explanation:
This function resembles that of the absolute value function, never going into the negative y values. Hope this helps!
If you are rounding it to the nearest tenth then it would be 60% because the unit is above 5.
Answer:
reflection over x axis then horizontal stretch by factor of 8/5
Step-by-step explanation:
f(x)=x
h(x) = -f(x) ... reflection over x axis (x,y) -> (x,-y)
-f(x) -> g(x) = (-5/8x) ...0 < |5/8| <1 ... horizontal stretch (x,-y) -> (x / (5/8) , -y)
