Question

Two linear functions, f and g, have the same y-intercept. Function f has a slope that is half the slope of function g.
Which of the following is not true?
A. The functions have the same rate of change.
B. The functions cross the y-axis at the same point.
C. Function g has a greater rate of change than function f.
D. The graphs of both functions are straight lines.

Answer 1

Which can we eliminate ?

Answer 2

a is correct because the they will both cross on the y-axis, function g does have a greater slope as a result of the slope being bigger, and they will both be stright lines because the slope intercept form formula does dont allow for curved lines

Answer 3

thank you :)
