• They have the same slope.

• They are parallel lines.

• They have the same y-intercept.

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?
