from the question, (-2,2) and (1,2) have the same y value so you can use that as your base and easily find the perpendicular height using the y axis since it's parallel to the x axis.
the third point, (0,-6), to the base is your height
use the sum of the positive of the y values to find your height (because height can't be negative): 6+2 = 8
area of a triangle = 1/2 bh = 1/2 x 3 x 8 = 12
Note: 1/2 bh only works because (-2,2) and (1,2) form a line parallel to the x axis

Answer
140.29 miles
Step-by-step explanation:
477miles/ 153 gallons = <em>x</em> miles/45 gallons
criss-cross multiplication and solve for x
477 x <em> 45 = 153 x</em>
x = (45x477) / 153 = 140.29 miles
The overall total of the group of golfers is 3 over par or (+3).
In order to find this, we just need to add the numbers together.
2 - 3 + 5 + 0 - 1 = 3
