In the xy-plane, the points and lie on the graph of which of the following linear functions?
A
B
C
D
Correct answer: C
Explanation
Choice C is correct. A linear function can be written in the form , where m is the slope and b is the y-coordinate of the y-intercept of the line. The slope of the graph can be found using the formula . Substituting the values of the given points into this formula yields or , which simplifies to . Only choice C shows an equation with this slope.
Choices A, B, and D are incorrect and may result from computation errors or misinterpreting the given information.
