Free points!!

May I please get someone who can explain this to me.

Step-by-step explanation:

1) y = 4x +3

When x = 1 , y = 4*1 + 3

                       = 4 + 3

                        = 7

(1 , 7)

when x = 3,    y =4*3 + 3

                         = 12 +3

                         = 15

(3 , 15)

Mark (1 , 7) & (3 ,15)  on the graph and find another point on the line

2) y = 3/2 x - 1

When x = 2 ,

                        = 3 - 1

                        = 2

(2 , 2)

When x = 4 , y =

                       = 3*2 -1

                       = 6 -1

                       = 5

(4 , 5)

Mark (2 ,2) & (4 ,5)  on the graph and find another point on the line

i am thinking c. sorry if im wrong .
