please help me with the grade

Answer:
C. y= -5x + 6
Step-by-step explanation:
this is really simple, all you have to do is to substitute the appropriate values of x and y into the equation
checking for the first one, A
16=-⅕x + 6
80= -x+30
80-30=-x
x= -50
so the answer isn't A
checking for B
11= 6x-1/5
55=30x-1
54= 30x
x= 54/30=27/15=9/5
so the answer isn't B
checking for C
1=-5x+6
1-6=-5x
-5= -5x
x= 1
therefore the answer is C
