Answer:
y = x - 4
Step-by-step explanation:
In y = ax + b form, a is the slope and b is the y intercept so a = 1 and b = -4, thus y = x - 4
Tank A capacity = 550 gallons 66% x 550 gallons = 363 gallons in Tank A
How about the water in tank B?
ratio of 11: 15 11/15 = 550/x 550 * 15/11 = cap B = 750 gal 53% 0f 750 = .53 x 750 = 397.5 gal in tank B
D is the answer because rise over run is going to left and plus 2 is on the y axis
