Answer:
A. (-3,4), (6,2), (-7,1), (2,2)
Step-by-step explanation:
Functions cannot have the x repeating. All the other answers have one of their x-values repeating, so they are not functions.
The file includes the input of your equation, comment if the equation you input is a mistake.
y=-3/5x+16
m=(y2-y1)/(x2-x1)
m=(13-19)/(5-(-5))
m=-6/(5+5)
m=-6/10
simplify
m=-3/5
y-y1=m(x-x1)
y-19=-3/5(x-(-5))
y-19=-3/5(x+5)
y=-3/5x-15/5+19
y=-3/5x-3+19
