Answer:
Slope = 2
Y-Intercept = 4
Equation of Line is y=2x+4
Step-by-step explanation:
y-intercept is the point in the y-axis, where the line cuts it. So, looking at the graph, the y-intercept would be y = 4
To figure out the slope, we take any two points and calculate using the formula:
Where, m is the slope
is the first coordinate, and
is the second coordinate
<em>Let's take two points as: (-2,0) & (-1,2)</em>
<em />
Plugging these into the formula we get the slope as:
Hence slope is 2
Equation of the line is given as y = mx + b, where m is the slope (in our case 2) and b is the y-intercept (in our case 4). Thus:
Equation of Line: 
The formula for the sum of the a finite geometric series is this:
Sn = a((1-r^n) / (1-r))
The given values are:
n = 30
a = 0.5 mi
r = 1.10 (10% more each day)
S30 = 0.5 ((1-1.10^30) / (1-1.10))
S30 = 82.25 mi
After 30 days, he will have traveled 82.25 miles.

Answer:
When the plane makes its turn to fly southeast, it makes a 45º angle at point a, making angle abc also equal to 45º.
Line ab is the 2 miles southeast the plane flies.
Line ac = line cb
sine (45º) = opposite / hypotenuse = cb / 2
.70711 = cb / 2
cb = 1.41422 miles = line ac
Line cs = 3 - 1.41422 = 1.58578
Line x^2 = cs^2 + cb^2
Line x^2 = 2.5146982084 + 2.0000182084
Line x^2 = 4.5147
Line x = 2.1248
