1. Two linear functions, A and B are described by

y=f(x)=ax+b.

For function A, the y-intercept value is negative two and the ratio of the change in y-values to change of x-values is four.

For function B, the line passes through two coordinates of points (0, -3) and (1.5, 0).

In comparing the rates of change, which statement about the lines described by function A and function B is true?


a.
The lines described by function A and function B both have negative slopes.

b.
The line described by function A has a negative slope and the line described by function B has a positive slope.

c.
The lines described by function A and function B have the same slopes.

d.
The line described by function A has a greater slope than the line described by function B.
