Answer:

Explanation:

1.

y=mx+b

slope=m=3 (4,2)

Hence y=3x+b (1)

We substitute valueы of x=4 and y=2 into the equation (1):

2=3(4)+b

2=12+b

2-12=12+b-12

-10=b

Thus, b=-10

Hence y=3x-10

2.

y=mx+b

slope=m=-2 (0,3)

Hence y=-2x+b (1)

We substitute valueы of x=0 and y=3 into the equation (1):

3=-2(0)+b

3=0+b

3=b

Thus, b=3

Hence y=-2x+3

3.

y=mx+b

slope=m=-1 (1,-7)

Hence y=-x+b (1)

We substitute valueы of x=4 and y=2 into the equation (1):

-7=-(1)+b

-7=-1+b

-7+1=-1+b+1

-6=b

Thus, b=-6

Hence y=-x-6

And so on ...
