Proportional Relationship Slope

What is the unit rate/constant rate of change?

• 80 mph

• 20 mph

• 40 mph

• 160 mph

Find the slope:

• 2

• -2

• 1/2

• -1/2

If you calculated slope and got "m = 5/0". What would be the slope of the graph?

• Positive, because 5/0 = 5

• Zero, because 5/0 = 0

• Undefined, because 5/0 doesn't give you an exact answer.

Which equation best represents the line on the graph?

• y= 1/2x

• y= -1/2x

• y = 2x

• y = -2x

In the equation y=mx, what does the m represent?

• slope

• y-intercept

• linear

• point-slope

What is the slope of the line with the equation y = 2/3x ?

• 2/3

• - 2/3

• 3/2

• -3/2

What is the slope of the line with the equation y = 4x

• 4

• 1/4

• -4

• -1/4

Does this graph represent a proportional relationship?

• Yes, because the line is pretty.

• No, because the line goes through the origin.

• Yes because the line goes through the origin.

• No, because the graph is non-proportional.

What is the 1st step when finding the slope from a table?

• Find the INITIAL VALUE

• Find the pattern in the x-values (change in x)

• Find the pattern in the y-values (change in y)
