Consider the following equations:

−x − y = 1
y = x + 3

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

a: (−1, 2)

b: (−2, 1)

c: (1, −2)

d: (2, −1)

Line gh passes through points (2, 5) and (6, 9). which equation represents line gh? y = x + 3 y = x – 3 y = 3x + 3 y = 3x – 3

The first few steps in solving the quadratic equation 9x2 + 49x = 22 ? 5x by completing the square are shown. 9x2 + 49x = 22 ? 5x 9x2 + 54x = 22 9(x2 + 6x) = 22 which is the best step to do next to solve the equation by completing the square? 9(x2 + 6x + 3) = 25 9(x2 + 6x + 3) = 49 9(x2 + 6x + 9) = 31 9(x2 + 6x + 9) = 103

Graph the following system of linear inequalities. identify at least two points in the solution: y < 5 - 2x | x + 5y > -7
