Determine the equation of a circle whose diameter has the endpoints (–1, 2) and (7, –4). 1) (x – 3)2 + (y + 1)2 = 100
2) (x – 3)2 + (y + 1)2 = 5
3) (x – 3)2 + (y + 1)2 = 25
4) (x – 3)2 + (y + 1)2 = 10

Question: a) does the given set of points represent a linear function? how do you know? b) assume that the point (-2,4) lies on the graph of a line. what y-values could complete this set of ordered pairs that lie on the same line: (- (hint: there are several correct answ
