Math Problem Statement
Which of the following points does not lie on the line y = 3x − 2?
A
(0, −2)
B
(1, 1)
C
(−1, 5)
D
(2, 4)
Solution
To determine which point does not lie on the line , we substitute the - and -values of each point into the equation and check if the equation holds true.
Testing each point:
-
Point A:
Substituting into :
The -value matches (), so lies on the line. -
Point B:
Substituting into :
The -value matches (), so lies on the line. -
Point C:
Substituting into :
The -value does not match (), so does not lie on the line. -
Point D:
Substituting into :
The -value matches (), so lies on the line.
Conclusion:
The point that does not lie on the line is C: .
