Answer:
y=-0.4x-1
Step-by-step explanation:
lets write the equation of the perpendicular graph: y=2.5x+1
Two graphs are perpendicular if the multiplication of their slopes are equal to -1.
So we can say that: 2.5*x=-1 → x=-0.4
Now we will find the needed graph with the help of the slope and the point (0,-1):
y-(-1)=-0.4*(x-0) → y+1=-0.4x → y=-0.4x-1

Answer:
b
Step-by-step explanation:
The statement which is true in the choices is the third item in the choices such as "Nina makes 20x dollars at the clothing store each week". It was clearly stated in the given that x represent the total number of hours she worked in a week. This statement made the other items in the choices wrong.
9.25= 9 1/4
.25 equals 1/4!
