• Not a constant slope/Non-Linear

what is the slope of the table (hint think back to the pretest)

• 1

• 2

• 11

• Not a constant slope/Non-Linear

What is the rate of change (slope) of the line shown?

• 40/1

• 50/1

• 10/1

• 1/10

When y=\frac{2}{3}x and y=\frac{2}{3}x+4 are graphed on the same coordinate plane, how are they related to each other geometrically?

• They have different starting points (y-intercepts).

• They have different slopes.

• They have the same slopes and will create intersecting lines.

• They have the same slopes and will create parallel lines.

•   $y=\frac{2}{3}x$  is a translation of  $y=\frac{2}{3}x+4$  4 units down.

Which situation could be represented by the graph above?

Which situation could be represented by the graph above?

• The amount of money, y, in a cash box after x tickets are purchased for carnival games. The slope of the line is  $\frac{1}{4}$  and the y-intercept is 7 .

• The amount of money, y, in a cash box after x tickets are purchased for carnival games. The slope of the line is  $\frac{1}{4}$ .

• The amount of money, y, in a cash box after x tickets are purchased for carnival games. The slope of the line is  $\frac{4}{1}$  .

A linear relationship is

• always a positive line.

• a relationship between two quantities

• always a negative line.

• one quantity has a constant rate of change with respect to the other.
