Answer 1

When y-intercept changes, you just shift the line up and down.

Answer 2

Showing some example of shifts,

SHIFTS:

f(x)= ∜x ⇒ f(x)= ∜(x \(\normalsize\color{blue}{ +~\rm{c} }\) ) , c units left.

f(x)= ∜x ⇒ f(x)= ∜(x \(\normalsize\color{blue}{ -~\rm{c} }\) ) , c units right.

f(x)= ∜x ⇒ f(x)= ∜(x )\(\normalsize\color{blue}{ -~\rm{c} }\) , c units down.

f(x)= ∜x ⇒ f(x)= ∜(x )\(\normalsize\color{blue}{ +~\rm{c} }\) , c units up.

Answer 3

And same is here,

\(\normalsize\color{blue}{ y=mx+b ~~~~~~~⇒~~~~~~~ y=mx+b\color{red}{ +b} }\) (whether ` b ` is positive or negative, you can see that it is a VERTICAL SHIFT, right ?

Answer 4

yeah so its a,c,e?

Answer 5

Close, it is just \(\normalsize\color{blue}{ a }\) and \(\normalsize\color{blue}{ c }\)

Answer 6

You can exclude C, because you can't Stretch a line in this way. You can change the diagonal of it...
