You need to solve a system of equations. You decide to use the elimination method. Which of these is not allowed?
2x - 3y = 12
Equation 1
-2x + y = 8
Equation 2
A. Add the left side of equation 2 to the left side of equation 1.
O B. Add equation 2 to equation 1.
C. Multiply equation 2 by 3. Then subtract the result from equation 1.

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.
