Explanation:
To discover out if a suggest (x, y) is on the graph of a line, we plug in the values and also view if we gain a true statement, such as 10 = 10. If we acquire somepoint various, favor 6 = 4, we understand that the suggest is not on the line because it does not fulfill the equation. In the offered choices, as soon as we plug in (1, 10) we get 10 = 7 + 2, which is false, making this is the preferred answer.
You are watching: For the straight line defined by the points
y = 7x + 2
(2, 16) provides 16 = 7(2) + 2 = 14 + 2 = 16
(–1, –5) offers –5 = 7(–1) + 2 = –7 + 2 = –5
(0, 2) gives 2 = 7(0) + 2 = 0 + 2 = 2
(–2, –12) provides –12 = 7(–2) + 2 = –14 + 2 = –12
All of these are true.
(1, 10) offers 10 = 7(1) + 2 = 7 + 2 = 9
10 = 9 is a false statement.
