Use the sliders to set y1 = y2 to make a horizontal line. Move the x1 and x2 sliders back and forth. 5. What is the slope of a horizontal line? Does every horizontal line have the same slope? Why? 6. Which axis are all horizontal lines parallel to? 7. Use the sliders to set x1 = x2 to make a vertical line. Move the y1 and y2 sliders back and ...

Slope = y2 - y1 = rise . x2 – x1 run . Students should also recall that a positive slope rises from left to right, a negative slope falls from left to right, a slope of zero is a horizontal line, and a vertical line has an undefined slope. Complete the table and then graph the line for the equation y = x – 4. ...

Slope Formula: _y2 – y1_ x2 – x1. m1 = m2 that the lines are perpendicular, show that the slopes are negative reciprocals. Slope Formula: (see above) Products of slopes = -1 Methods that can be used to Prove that a
Slope Activity for Algebra I - Texas Instruments
Students should know two ways to find slope: Rise and y1- y2. Run x1- x2. Break students up into groups of four and have them log into navigator. The teacher should plot a line using activity center and have one group pick out four nice points so the rest of the class can determine the slope by rise over run and by using the slope formula.

Since y1 = y2 = y3 = 2 m we can cancel the common y values from the numerator of the central equation above and insert the values of b1 = 4 m and b2 = 8 m obtain the following equation. We see that the equations will be dimensionally consistent if b3 is in meters. Omitting the dimensions, we can obtain the following computational equation.
