8.8.2-Develop Showing that the Slope of the Line is Constant

Multiple Choice

True or False:

Is the following graph proportional?

• True

• False

Multiple Choice

A proportional relationship is written used which of the following equations?

• $$y=kx$$  

• $$y=kx+b$$  

Multiple Choice

What is the slope (in miles per hour) based on the table?

• 45

• 90

• 135

• 2

​Think about this...
y = kx + 0
or
y = mx + b
What does the k stand for/m stand for?
What does the 0/b stand for?

​Underline each set of directions (separate colors).

​Think about dilations. Our rule for dilations looks something like this:

(x + . y + _) or (x - _. y - _)
(positive slope) or (negative slope)

​m = y /x
