Match each system of equations to its point of intersection. y = 2x + 1 y = x + 3 y = x + 3 y = -3x − 2 y = -x − 7 y = x + 3 y = -x − 7 y = 2x + 1 y = 2x + 1 y = -3x − 2

Robert plans to make a box-and-whisker plot of the following set of data. 27, 14, 46, 38, 32, 18, 21 find the lower quartile, the median, and the upper quartile of the set? lower quartile: 19.5; median: 29.5; upper quartile: 42 lower quartile: 14; median: 27; upper quartile: 46 lower quartile: 18; median: 27; upper quartile: 38 lower quartile: 16; median: 29.5; upper quartile: 42
