5.5 Slope on axes with 1:1 Ratio

Estimate Slope

Estimate the slope of the line segment.

Use the following for reference:

A flat line – slope zero

A line at 45 degrees to the horizontal – slope 1 or -1

A vertical line – infinite (or undefined) slope.

Use the style bar icon at the top right to turn on the grid.

Move the line segment to create a certain slope

Use the applet to create line segments of the following slopes:

  1. Slope AB = 5
  2. SlopeAB = -3
  3. Slope AB = 0
  4. Slope AB = 1
  5. Slope AB = -1
  6. Infinitely steep
  7. Slope AB = \frac{5}{2}
  8. Slope AB = -\frac{1}{4}

Skill #2

Determine the slope of each line segment. Note that the scale on each axis is one unit for each box.
