Select the correct choice below and fill in the answer box to complete your choice
Round to the nearest whole number as needed.)

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.

Find the solution(s) to the system of equations. select all that apply y=x^2-1 y=2x-2
