Line segment
a. a series of points that extend in two directions without end plane
b. two lines that intersect at 90° angles perpendicular lines
c. lines that lie in the same plane and do not intersect line
d. a flat surface that extends infinitely and has no thickness parallel lines
e. part of a line that has two endpoints

Look at this system of equations. -3x + 3y = 12 y = x + 4 the solution set of this system is best explained by which of these statements? a) the graphs of the equations are the same line because the equations have the same slope and the same y-intercept. the system has infinitely many solutions. b) the graphs of the equations are parallel lines because they have the same slope but different y-intercepts. the system has no solution. c) the graphs of the equations are lines that intersect at one point because the equations have the same slope but different y-intercepts. the system has exactly one solution. d) the graphs of the equations are lines that intersect at one point because the equations have the same slope and the same y-intercept. the system has exactly one solution.
