Tiger shark:
2240 miles in 28 days = 80 miles/day

GW shark:
2368 miles in 32 days = 74 miles/day

80 miles/day x 32 days = 2560 miles the Tiger shark would have traveled

2560-2368 = 192

If the tiger shark had traveled at the same rate for 32 days, the tiger shark would have traveled 192 miles more than the great white shark

The ordered pair (- 3, 1 ) is a solution to the second equation because it makes the second equation true

To test , substitute the coordinates of (- 3, 1) into the equations and if both sides are true then it is a solution to the equation.

x - 4y = - 3 - 4 = - 7 ≠ 6 ← not true

(3 × - 3) + 1 = - 9 + 1 = - 8 ← true

Thus (- 3, 1 ) is a solution to the second equation
