a. \( y = 4 x + 1 \)                                    e. \( y = \frac { 5 } { x } \) 

b. \( y = x \)                                                 f. \( y = \frac { x } { 5 } \) 

c. \( y = 4 x ^ { 2 } + 13 \)                               g. \( y = 10.3 x + 60 \) 

d. \( y = \frac { 1 } { 3 } x - 5 \)                                   h. \( y = 3 \sqrt { x } + 1\)
