Question

i need Algebra Help!
metal And A fan!

Answer 1

i think its a /.\

Answer 2

Hold on lemme see.....

Answer 3

You know that the only choices with perpendicular slope are C and D.

The question is the y-intercept at which this perpendicular line would be passing through (-1,7).

So... just say
y=4x+b plug in your point.
7=4(-1)+b
7=-4+b
11=b

So, you found the y-intercept to be 11... RE-write the equation...

y=4x+11

Answer 4

ohh i was kinda close lol so its D?

Answer 5

need help

Answer 6

yeah on this question, hold on

Answer 7

its c

Answer 8

Well, by "function" in your question, do you that it must be a linear function, or can be exponential or other as well ?

Answer 9

what?

Answer 10

Have you ever heard that a function can be a

"linear function", or a strait line
"exponential function" a curve
function that represents a shape (forgot the exact name, but) for example a parallelogram can as well be a function (but not linear of course).

Answer 11

so it is C ?

Answer 12

and i think i have that in my notes

Answer 13

So, in your question... in order for the table (A or B) be a function it must be linear?
Alright, I'll assume so, - it must be linear...

Answer 14

Table A

y x
3 1
2 0
1 0

is not a function, because the only way you get (2,0) and (1,0) in a linear function is a line y=0, but the 1st point, (3,1) is not on the y=0.

Answer 15

table B

y x
3 -2
3 1
5 2

the only time you can get (3,-2) and (3,1) is on the line x=3... HOWEVER (5,2) is not one of the points on x=3.

Answer 16

The answer is B.

Answer 17

thank you! imma take notes of all of this !

Answer 18

:) You welcome !

Answer 19

But this is without a background... if you want, I can give you a better idea of what a function and all of that staff .

Only if you want though, you don't have to .
