The slope is -5/4
Slope formula being y2-y1/x2-x1 = 7-(-3)/-9-(-1)
Quotient means division, so you can immediately throw out C as an answer choice. the order of this question is important because it lists it exactly how you're supposed to write it: the quotient of 3 and m, which is 3 divided by m.
your answer is B. 3 divided by m equals 1.9!!
1. 0 - 34 + 13 - 5 = -26.....26 ft below the surface
2. y = 15x + 50
220 = 15x + 50
220 - 50 = 15x
170 = 15x
170/15 = x
11 1/3 = x......he worked 11 1/3 hrs.......not sure about this...because it does not specify how many visits he made...but if this was just for 1 visit, then he worked 11 1/3 hrs
