Answer:
D. y = 2x + 1
Step-by-step explanation:
To find the slope, you first have to find the change of y over x, and in this case, you can plainly see that each one is equal to 2. So, that means that the slope is 2. You then can use the slope to find y when x is equal to 0. In this case, y = 1 when x = 0, so that means that the y-intercept is 1. Hence, the final answer is D.

Answer:
force of gravity is kind of force that pulls things towards the center of earth
X is independent because none of the other numbers or variables affects it
This is like the equation of a line where y is the area, x is the time, and 8.5% is your slope. So you have y=0.085x+b (reason why I switched 8.5% into 0.085 is because that is how you write a percent as a decimal).So now you need to find what b is. So you know orignally the area is 2400km^2 at x=0 years (this is what it is initially).If you plug those numbers in you have:2400=0.085(0)+bThen after solving for b, you can write your equation as:y=0.085x+(whatever you found b to be)Then plug 13 in for x and you have your answer. y=-.085(13)+2400
