Question

Which point lies on the line described by the equation below?
y + 4 = 4(x - 3)

Answer 1

I'm assuming you have choices?

Answer 2

a(2, 9) b(3, -4) c(1, -11) d(1, 11) e(0, 0) f(-2, 3)

Answer 3

That's better... Now here's how to do it, check each point (there's no other way, unfortunately)....
for example, a. (2 , 9)

Now, replace x with 2, and y with 9
And see if things "make sense"
9 + 4 = 4(2 - 3)
13 = 4(-1)
13 = -4

And it doesn't make sense (it should lead to a reasonable equation, like 6 = 6)

So a(2,9) is not the answer :P

Go now, try the others...

Answer 4

Thanks again (:

Answer 5

No problem :)
