Question

PLEASE HELP :( PLEASEEE :/
Which of the following points are on the line given by the equation y = -3x +5? Check all that apply.

A. (-2, 11)
B. (3, -14)
C. (2, -1)
D. (-3, 14)

Answer 1

im a little confused :/

Answer 2

use the quadractic formula\[y=mx+b\] start with the point on the y- axis (the b in the equation) then use the rise and run of the m.. on graph.. use should be able to see it. If you give me what u think it might be, I'll let you know if you're right

Answer 3

That's the slope y=mx+b

Answer 4

Let me give you a little hint.

Answer 5

b is the point on your y-axis

Answer 6

So one coordinate is (0, 5)

Answer 7

Do you understand?

Answer 8

Wow. Only one doesn't apply o:

Answer 9

Don't give it to her

Answer 10

Oreo do you understand?

Answer 11

Take the x- and y-coordinates of each point and plug them in for x and y in the equation of the line. If that makes the equation is true, then the point is on the line.

Answer 12

I'm not, i'm waiting for everyone to say what their going to say. Lol.

Answer 13

oops that's right.. so sorry.. quadractic is \[a^{2}+b^{2}=c ^{2}\] the explaination on how to use the slope is correct

Answer 14

@mathstudent55 Good Explanation :3

Answer 15

@Oreoo are you there?????

Answer 16

How are we supposed to help

Answer 17

Person waits til we say answer then says thanks. Usually how it goes.. Lol.

Answer 18

Answer 19

im doing my work ok lol

Answer 20

lol.. wish my question was getting this much traffic

Answer 21

I don't see it I'll go help

Answer 22

Mathstudent, gave you exactly what you needed to know to find the answer.

Answer 23

Here, I'll show you a example.

Answer 24

Say, you have (9, 20) as your choice.
9 is x, 20 is y. your equation is: y = -3x + 5 plug in: 20 = -3(9) + 5
20 = -22 Doesn't equal; means it's not on the line.

Answer 25

Now, i'll show you one that applies, but the rest you will have to plug in on your own and ill confirm if you did them correctly.
A) -2, 11 -2 is x 11 is y
y = -3x + 5
11 = -3(-2) + 5
11 = 6 + 5
11 = 11
Equal amount; is a point on the line according with the equation given.
Now try the 3 other choices and tell me what you get.

Answer 26

is a?

Answer 27

i mean i got a

Answer 28

Hmm, you must read your question again.
CHOOSE ALL THAT APPLY!
So, you must check the other 3.

Answer 29

11=-3(-2)+5
11=11

Answer 30

oh yeaaa
lol i forgot

Answer 31

Now, try the other 3 and tell me what you get.

Answer 32

i got all except for b

Answer 33

Perfect.
