What are 2 ways to find out if a couple planning on having 3 children, WON'T have any boys?

Give me the equations of two lines that have the same slope but are not parallel.

If a || b and e || f , what if the value of y ?

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.
