se a^2- b ^2 = (a-b) (a+b), então (a+b) (a-b) = a ^2 - b ^2. Escreve o produto da soma pela diferença de dois termos

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.
