Question

Line R is represented by the following equation: x + y = 2

Which equation completes the system that is satisfied by the solution (1, 1)?

2x + y = 2
4x − 2y = 2
2x − 2y = 2
x + y = 4

Answer 1

(1,1) is the solution so it must satisfy the two equations:

1st one x + y =2 and 1 + 1 =2 so that is good.

With me so far?

Answer 2

yes

Answer 3

now put in x=1 and y=1 into the choices to see which eqn is good :)

Answer 4

b..?

Answer 5

u didnt put letters in front of ur choices, @automaticloveletter :P

but yes, b is the right ans!

Answer 6

i did it in my head lol but thanks!

Answer 7

welcome :)

Answer 8

@sdfgsdfgs can you help me with some more?

Answer 9

sure @automaticloveletter just post the prob :)

Answer 10

Based on the graph, which statement is correct about the solution to the system of equations for lines A and B?

(4, 4) is the solution to line A but not to line B.
(4, 4) is the solution to both lines A and B.
(5, 1) is the solution to line B but not to line A.
(0, 2) is the solution to both lines A and B.

Answer 11

is there a graph?

Answer 13

OK, read the choices n tell me what u think plz :P

Answer 14

b?

Answer 15

correct :)

Answer 16

Which description best describes the solution to the following system of equations?

y = −x + 4
y = 3x + 3

Line y = −x + 4 intersects the line y = 3x + 3.
Lines y = −x + 4 and y = 3x + 3 intersect the x-axis.
Lines y = −x + 4 and y = 3x + 3 intersect the y-axis.
Line y = −x + 4 intersects the origin.

Answer 17

@automaticloveletter u should know the ans already :P

Answer 18

i'm very clueless /: a?

Answer 19

@automaticloveletter u said clueless n yet got the right ans :P

Answer 20

cuz i am xD

Answer 21

A pair of equations is shown below.

x + y = 5
y = one halfx + 2

If the two equations are graphed, at what point do the lines representing the two equations intersect?

(2, 5)
(5, 2)
(2, 3)
(3, 2)

Answer 22

this one u actually have to solve the solution....feel like do it @automaticloveletter ?
