Answer:
Linear
Step-by-step explanation:
For every step in x, the y values increase by 4 each time, making it a linear function, since the change in y is constant.
y=3x+38 is the expression for Sidney's weekly salary.
Step-by-step explanation:
Given,
Casey's weekly salary = x
Let,
y be the weekly salary of Sidney's.
According to given statement;
Sidney makes $38 more than 3 times Casey's weekly salary.
Sidney's weekly salary = 3 times Casey's weekly salary + $38

y=3x+38 is the expression for Sidney's weekly salary.
