Evaluate m – n when m = –2.6 and n = 7.9.
a. –10.5
b. –5.3
c. 5.3
d. 10.5

M = -2.6

n = 7.9

Thus, 

m - n = -2.6 -7.9 = -10.5

The answer is A.

(6,1)(5,4)slope = (4 - 1) / (5 - 6) = 3/-1 = -3y = mx + bslope(m) = -3use either of ur , = 6 and y = 1now sub and find b, the y int1 = -3(6) + b1 = -18 + b1 + 18 = b19 = bso ur equation is : y = -3x + we need it in standard formy = -3x + 3x to both sides3x + y = 19 < == standard form
