Well in my calculations I got: well if you he increases the speed by 2.6 per hour soo 4+2.6=6.6
To find the slope use the Rise over Run rule
It rises 2 units and runs 1 unit, so your slope is
2 or 2/1
To find the y-intercept just find where the line crosses the y-axis
it crosses at the -4 mark
Your slope is 2 and y-intercept is -4
Only i.
If the value is changing by a certain dollar amount every year, this means it is a constant rate of change. If it is changing by a certain percentage every year, this means it is changing at a non uniform, specifically exponential, rate.
The answer is B
hopefully this helps
The answer is around 79, but if you want to round it, you could round it up to 80.
