Wendy has 8 seashells in her collection. She has 122 of each kind of shell. How many shells does Wendy have in her collection?

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.

Which steps could be part of the process in algebraically solving the system of equations, y+5x=x^2+10 and y=4x-10
