The answer would be m = -1/7 or -0.143
Since we are given the value of b (-3) and a coordinate (7, -4), All you have to do is plug the x-coordinate into x and the y-coordinate into y; simplifying the equation to (-4 = m*7-3). Using simple algebra, find m by adding 3 to -4. Finally, divide that by 7 to get your final answer, (-1/7).

Species A: 18.9 miles / 42 minutes = 0.45 miles per minute
Species B: 20.3 miles / 58 minutes = 0.35 miles per minute
Therefore, species A is faster and flies at a speed of 0.45 miles per minute
(27 mph)
0.45 x 60 = 27 mph
Distribute
3k-18=15
Get k by itself, add 18 to both sides
3k=33
Divide by 3 to both sides to make k by itself
k=11
