Answer:
(8, - 2 )
Step-by-step explanation:
A translation of 4 units right means add 4 to the x- coordinate
A translation of 5 units up means add 5 to the y- coordinate
(x, y ) → (x + 4, y + 5 ) ← translation rule, then
(4, - 7 ) → A'(4 + 4, - 7 + 5 ) → A'(8, - 2 )
Answer:
Yes
Step-by-step explanation:
The domain is {-19, 19}
The range is {0,16}
We can write as ordered pairs to obtain:
(-19,0), (19,16)
None of the first coordinates of the ordered pairs repeats.
Hence the relation represents a function.

Slope intercept form equation:
y=mx+C
----------------------
We already know that m=-4. Now, let's find the value of C.
--------------------
m=-4, and when x=-1, y=5.
(5)=(-4)*(-1)+C
5=4+C
5-4=4+C-4
1=C
-----------------
Therefore the slope intercept form of the function is:
y=-4x+1
