Lines in Motion. Lesson 4.3. Earlier you worked with two forms of linear equations: Intercept form : y = a+bx Point- slope form : y=y 1 +b(x-x 1 ) In this lesson you will see how these forms are related to each other graphically.
At 0 seconds the student begins to walk at the rate of ½ meter per second toward point A. Record the time and distance of the student from position A for the first 5 seconds.
At time 5 seconds, the student will momentarily stop and then begin walking backwards at the same rate.
For time 5 -10 seconds, record the time and distance the student is from both point A.
For the second path, have a second student again walk at ½ meter per second, but begin at time 0 seconds where the first student was at time 2 seconds on the first walk. Record the time and how far the this student is from position B.
For the first three seconds the student should walk forward for and then momentarily stop and then begin walking backwards at the same rate.
For the next 7 seconds record the time and position the student is from position B.
