Step-by-step explanation:

b) y=35x

Step-by-step explanation:

Since we have a linear function, with b=0 in the form y=mx, then line passes through the Origin (0,0).

We can see y=35x it's the only function with b=0.

Algebraically, let's test it to find out the initial value for x in this function.

y=0

y=35x

0=35x

x=0/35

x=0

(0,0)
