1. Determine the slope of a line that is perpendicular to the linear equation (Record your answer in the numerical-response section below.) Your answer: O000 Numeric Response 2. What is the value of x-intercept for the graph of 2z - 4y – 36 = 0? (Record your answer in the numerical-response section below.) Your answer. O000 Numeric Response 3. An equation of a line is kz – 7y+12 =0. If the line passes through the point (2, 8), then the value of k is
Permutations and Combinations
If there are 5 dishes, they can be relished in any order at a time. In permutation, it should be in a particular order. In combination, the order does not matter. Take 3 letters a, b, and c. The possible ways of pairing any two letters are ab, bc, ac, ba, cb and ca. It is in a particular order. So, this can be called the permutation of a, b, and c. But if the order does not matter then ab is the same as ba. Similarly, bc is the same as cb and ac is the same as ca. Here the list has ab, bc, and ac alone. This can be called the combination of a, b, and c.
