Two angles are supplementary. the first angle measures 40°. what is the measurement of the second angle?
a. 50°
b. 140°
c. 120°
d. 60°
6. which of the following best describes a plane?
a. the point of intersection of two walls
b. the edge of a desk
c. the surface of a flat table
d. a curve in a road

The first answer would be B 140 as supplementary angles add up to 180.

The next answer would be the surface of a flat table.

You need to be more specific.  i really don't know what a "motion map" is.you can draw a graph of an object's position, distance, displacement, speed,velocity, or acceleration versus time, or you can draw a graph of the object's x-position versus its y-position and not give any information about time at all.if the graph presents position or displacement against time,  then constant velocity is a straight line . . i.e. a line that has  constant slope.if the graph shows speed against time, then constant velocityis a horizontal piece of line.if the graph shows acceleration against time, then constant  velocity is a piece of line that lies on the x-axis . . it's value is zero.
