Answer:
4x
3x
Step-by-step explanation:
1.)
we see that when x=0 y=0 which means that our equation
y=mx+b
b=0
(this is shown if we plug in 0 for x)
0= 0x+b
0=b
Next, we notice that each time it's increasing by four which means our slope is just 4
the answer is 4x
The y intercept (or b) is the same deal as question one
we can also see that when x=1 y=3 which means that
3=x+0
3=x
our slope is 3
