Parallel Lines never intersect because...

• they have the same slopes.

• they have the same y-intercept.

• they have different slopes.

• they have different y-intercepts.

Two linear functions, f(x) and g(x) are represented. Compare the functions stating which has a greater rate of change. The function ​ (a)   has the greater rate of change. The rate of change is ​​ (b)   .

• g(x)

• 20.5

• -3

• 3

• -0.8

• f(x)

• 4

• -5/2

• -2/5

• 5.5

Which of the following is the best description of how the slope of r compare with the slope of s(x)?

• The slopes of r and s(x) are the same, so the lines are parallel.

• The slopes of r and s(x) are not the same, so the lines are not parallel.

• The slopes of r and s(x) are both negative.

• The slopes of r and s(x) are both positive.
