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?

    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)
