In the xy-plane, the points and
lie on the graph of which of the following linear functions?
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.
