Answer: 1,259 meters.
Step-by-step explanation:
GIven: The highest elevation in a small country occurs on a mountain above sea level = 1,232 meter
The lowest elevation in the same country occurs below sea level = -27 meters
The difference in elevation between the highest and lowest points = Highest - lowest
= 1232 - (-27) meters
= 1232+27 meters [ (-)(-)=(+) ]
= 1259 meters
Hence, the difference in elevation between the highest and lowest points = 1,259 meters.

Answer:
y= -3x+2
Step-by-step explanation:

Answer:
<h2>Explanation:</h2><h2>You know that when x = 0, y = -7 (because y = 4(0)-7 = -7, or you just know the fact that the constant number shows the y-value of the y-intercept). Therefore, you can plot that point on the graph:</h2>
