Question

Which point lies on the line?

Answer 1

I got y=3x+11 and put it in the calculator but nothing lines up.

Answer 2

it is not \(y=3x+11\) you forgot to distribute the \(3\)

Answer 3

So you DO have to distribute it? Ugh.

Answer 4

http://my.hrw.com/math06_07/nsmedia/tools/Graph_Calculator/graphCalc.html this is a graphing calculator

Answer 5

that is why it is called the distributive law, not the distributive option
it is not optional
multiplication distributes over addition always

Answer 6

I got it. It's y=3x+17

Answer 7

yes
although you really don't need to do this for the problem, it does make it easier
your job is to check all those points and see which one fits the equation

Answer 8

for example \((-2,13)\) is not the right answer because if \(x=-2\) then
\[y=3\times -2+17=-6+17=11\] not \(13\)

Answer 9

Thank you! I got it. :)

Answer 10

yw

Answer 11

did you get it ?
just sub in your answer choices into the equation and see which one is true.
I will try the first answer choice...
(-2,13)...x = -2 and y = 12
now sub
y - 8 = 3(x + 3)
13 - 8 = 3(-2 + 3)
5 = 3(1)
5 = 3 (incorrect)...so this one is not true.

just do the subbing like I just did and you should get your answer

Answer 12

oops..y = 13
