Given equation is


y=3x+22

a)

Substitute x=0 in the given equation, we get


y=3(0)+22=0+22=22

We get y=22.

The point is (0,22).

Substitute x=1 in the given equation, we get


y=3(1)+22=3+22=25

We get y=25.

The point is (1, 25).

Substitute x=2 in the given equation, we get


y=3(2)+22=6+22=28

We get y=28.

The point is (2, 28).

Substitute x=3 in the given equation, we get


y=3(3)+22=9+22=31

We get y=31.

The point is (3, 31).

Substitute x=4 in the given equation, we get


y=3(4)+22=12+22=34

We get y=34.

The point is (4, 34).

Hence the table is
