Question

A) in which quadrant does the point (-52, -35) lie.

B) Determine if the following points are solutions of the equation. (2,-3) , (-2,3) for 2x-y=7

Answer 1

Do you know where each quadrant is?

Answer 2

well it says consider each ordered pair.

Answer 3

yea it asks for the qaudrant?

Answer 4

huh mine does not have a graph. i get u though.

Answer 5

my key pad is missing up. guys im sorry about that.

Answer 6

Question a was about quadrants, those are the 4 different ones

Answer 7

yea i know i have to determine where i think -52,-35 belong at.

Answer 8

Well if you go left and then down, which one would you be in?

Answer 9

3

Answer 10

Thats correct

Answer 11

wat about the second part?

Answer 12

For that one you plug in the x coordinate for x and the y coordinate for y, and then if the equation equals 0 the point is a solution

Answer 13

yea because basically i mean ur just trying to solve how u get the answer. of the x and y. if u solve for x than y equals 0 and samething happens when u do for y right.

Answer 14

I misread that, plug those in and if it equal 7 then the point is a solution

Answer 15

so 2(2)-(-3)=7

Answer 16

no nevermind i think they cant be plug in right.

Answer 17

What do you mean?

Answer 18

I just plugged the first point into the equation

Answer 19

oh yea ok i was wrong ur right.

Answer 20

i get it now.

Answer 21

so is the first point a solution?
