Find the indicated dot product. r = < 9, -7, -8> , v = < 3, 4, 7> , w = < 6, -9, 7> v ? w (1 point) < -27, 28, 56> < 18, -36, 49> 18 31

Compare the subtraction problems 6/8 - 5/8 = 1/8 and 6/9 - 7/9 = 1/9 why is the answer to the first problem positive and the answer to the second problem negative

Lindsay used two points, (x,y; ) and (+2.82), to find the equation of the line, y = mx + b, that passes through the points. y2-y, first, she used the definition of slope and determined that the value of mis x, - . given this information, which expression must represent the value of b?

Any is very appreciated! (picture is provided below)not sure how to do this at all won't lie
