True/False [1 markeach = 12 marks] Indicate whether the statement is true or false. 1. The direction vector of a line is an indicator of its slope. 2. The dot product of two vectors results in another vector. 3. A runner's velocity, 15 m/'s 010, is an example of a vector. 4. The slope of a secant line represents the average rate of change. 5. When simplified, -(-1 -v) -3(-27 -4v) equals 77 + 137 6. The average rate of change of the function over the domain graphed is -2. (2, 6) 4 2 (-1, 0) 4 -2 0 2 4 X -2 7. For the graph below, lim f(x) = -. x - -2 2 -4 10 2 4 -2
