(a) compute the rank and nullity of the following matrices: 3 17 2 1) a = 0 3 -1 | 1-3 4 -2 (1 -1 b= 2 -2 4 10 0 c 3 1 1) = 6 2 2 19 3 3 ) -8 feel free to use the rank-nullity theorem. (b) determine which of the above matrices is invertible and compute their inverse clearly showing your calculations. (c) suppose that a is an m xn matrix and b is an p x m matrix satisfying rank(b) = p and null(b) = rank(a). show that null(a) = n - m + p. hint. use the rank-nullity theorem.

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
