A=-112 bcs -216 ft is down from sea level and -104 is also down from sea level bcs both values are in minus but -104 is higher than other so you can minus it from -216 the difference is the answer
b=-109
If she has half a pound of sunflower seeds and wants to split it into eight equal packets, each packet would be 1/16 of a pound. 1/16 of a pound is 1 ounce.
Therefore, each packet of seeds would weigh 1 ounce (1 oz.)
Subtract 14x from both sides. Then divide both sides by 19

The equation is now in slope intercept form y = mx+b
m = -14/19 is the slope
b = 20/19 is the y intercept
