Reasoning Solve the system of linear equations using substitution. Use pencil and paper Which express would be easier to substitute into the other equation, in order to solve this problem? Explain your reasonin
x=7y - 5
x + 7y=4

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.
