are you kidding ? all the question here

3. Suppose h(:13, y) is a linear function with h(1, 2) = 4, h(0, 3) = 3, and h(1, 3) = 5. Find the mslope m, the y-slope n, and an expression for h(:1:,y). (6 points) 4. Let 6' = (1,2,3) and 13' = (2,0,1) be vectors in R3. Compute each of the following. (12 points) (a) 317213 ((1) {J'X'LD' (b) '13 - 13' (e) The projection of '13 onto '6" (c) The angle between 17' and 11'} (f) \"13' 'u'J'll
