Nina had 17 marbles in a bag. her mother put a handful of marbles in the bag. when nina counts her marbles, she discovers she now has 34 of them. which of the following equations will nina solve for the number of marbles, m, that her mom put in the bag?

17 + 34 = m
17 + m = 34
17m = 34
m − 17 = 34

What is the slope of the line that contains the points (4,8) and (9,8)? what type of line is it?

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.
