Question 214169: It's not really about "graphing" actually...it's about a "whisker plot", could someone help me with it anyways??
I got a stem-and-leaf plot; 100, 92, 94, 95, 81, 82, 87, 89, 71, 71, 73, 61, 62, 68, 51, 55
mean= 1232/16= 77
mode= 71
median= 89+71/2= 160/2= 80
For the "whisker plot" I also need the first and third quartiles and dont understand how to get them, could someone explain to me how to find out what the first and third quartiles are?
I understood the rest...just didnt really catch how to get the first and third quartiles.

Question 219470: 1.Find an equation of a line that passes through the points (-2,-3) and (-1,1).
y=m(x-x1)+y1
y=4(x-(-2) + (-3)
y=4x +8 -3
y=4x + 5 (answer) Is this correct?
2. Find the equation of the line that contains the point (0,3) and is perpendicular to the line y=1/2X -1. My answer: y=-2x+1 Is this correct?
3. Find x intercept and y-intercept for the line with the equation y=4x + 1/2 and sketch the graph.
Y= 1/2
x= -2 Is this correct.
