The question is the which statement describes the relationship between the graph f(x) = 4x and the graph g(x) = f(x) + 3
The answer is option a. the graph of g(x) is translated 3 units up from the graph of f(x).
You can realize that every image of g(x) (this is the y-coordina) is the image of f(x) + 3 units, then all the y-coordinates of g(x) are 3 units upper than the y-coordinates of f(x).

Answer:
A = 21 cm²
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A = h (b₁ + b₂ )
where h is the height between bases and b₁, b₂ are the parallel bases
Here h = 3, b₁ = 9, b₂ = 5 , then
A = × 3 × (9 + 5) = 1.5 × 14 = 21 cm²
To find the slope use the formula
Y2-Y1
---------
X2-X1
(-1,-4) (1,4)
4- -4 = 8
-------------
1- -1 = 2
8/2=4 This will be your slope
Y=4x
Now we must figure out the y-intercept using the formula
Y-y1=slope(x-x1)
Y- -4= 4(x- -1)
Y+4= 4x + 4 The 4 distributes to the x and -1
Y=4x +4
-4
Y= 4x
This is your answer in slope intercept form.
P.S if you have a number minus a negative number it makes it a positive number
