In a proportional relationship, where k=1, what does y equal when x=5? A. 5
B. 1/5
C. 0.5
D. 0.2

5

Step-by-step explanation:

The question says a proportional relationship, of not stated otherwise, this means a directly proportional relationship, where,

y=kx

Now if, k=1, substituting in the equation would give,

y=x,

Therefore, whatever the value of x is, so is that the value of y,

thus, if x=5,

y=5
