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

(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?

- automaticloveletter

yes

- sdfgsdfgs

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

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.

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.

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)

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