Is the ordered pair, (-1,-2) a solution to the system of equations?
-2x-3y = 11
-X+y= -2

Need on this geometry question. explain how you did it.

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.

Complete the solution of the equation. find the value of y when x equals -5. -4x - 8y = -52
