HELP PLEASE

Answer 1

Question:

If the ordinate is three more than twice the abscissa and x E {-1,0,-1/3} which of the following sets of ordered pairs satisfies the given conditions?

Step-by-step explanation : -1,1),(0,3),(-1/3,7/3

Answer 2

The ordinate is three more than twice the abscissa
Ordnate: y; Abscissa: x
y=3+2x

x=-1→y=3+2(-1)=3-2→y=1→(x,y)=(-1,1)
x=0→y=3+2(0)=3+0→y=3→(x,y)=(0,3)
x=-1/3→y=3+2(-1/3)=3-2/3=(3*3-2)/3=(9-2)/3→y=7/3→(x,y)=(-1/3,7/3)

Answer: Option A) {(-1,1),(0,3),(-1/3,7/3)}
