Quadrilateral abcd has coordinates a (3, -5), b (5, -2), c (10, -4), d (8, -7). quadrilateral abcd is a

ab = sqr root (5-3)^2 + (-2+5)^2 = sqr root 13
bc = sqr root(10-5)^2 + (-4+2)^2= sqr root 29
cd= sqr root(8-10)^2 + +4)^2 = sqr root 13
da = sqr root(3-8)^2 + (-5+7)^2 = sqr root 29

When drawing a trend line for a series of data on a scatter plot, which of the following is true? a. there should be an equal number of data points on either side of the trend line. b. all the data points should lie on one side of the trend line. c. the trend line should not intersect any data point on the plot. d. the trend line must connect each data point on the plot.

Suppose you are going to graph the data in the table. minutes temperature (°c) 0 -2 1 1 2 3 3 4 4 5 5 -4 6 2 7 -3 what data should be represented on each axis, and what should the axis increments be? x-axis: minutes in increments of 1; y-axis: temperature in increments of 5 x-axis: temperature in increments of 5; y-axis: minutes in increments of 1 x-axis: minutes in increments of 1; y-axis: temperature in increments of 1 x-axis: temperature in increments of 1; y-axis: minutes in increments of 5
