Unformatted text preview: 13-9 The Graph of a Condition
A) Graph a. We mean a figure lying in the plane, that is, the set of points b. Thus angles, triangles and half planes are graphs, and so are segments, rays and lines
B) Conditions a. b.
c. (How are different?) d. e. f. g. h. i. j. k. l. m. n. Examples i. Sketch the intersection of the graphs of these four conditions and find the area
ii. The distance from a point P(x,y) to A(1,0) is equal to the distance P to B(7,0). Write an equation which expresses this condition. How many such points P are there? Sketch the set of all such points P. ...
