Question

Zombies scare everyone and a mummy is much like a zombie. In fact, their equations are parallel to each other. If the zombie equation is `y=7x+5` and the mummy equation passes through the point (3, 23), what is the mummy's equation?

Answer 1

y=-1/7+23 3/7

Explanation:

Since it's parallel you take the y=7x+5 and the 7 is turned into -1/7(to find what's PARALLEL)

Now you put it into point slope formula to get: y-3=-1/7(x-3)

Simplify the equation.

Hope this helps(^-^)

Answer 2

y=7x+2

Explanation:

you have your slope already so keep slope but remove 5 and turn it into b in order to solve for new equation ...

y=7x+b

sub in (3,23) in your equation

23=7(3) +b

23=21 +b

23-21=b

2=b

your new equation should be y=7x+2
