A. the graph represents a relation because it contains ordered pairs (x,y). It is also a function because there are no repeating x values.
B. (0,0) (8,6)
slope = (6 - 0 ) / (8 - 0) = 6/8 = 3/4
so ur equation is : y = 3/4x or f(x) = 3/4x <===
C. the variable x represents the height of the building and the variable y (or f(x)) represents the total length of the shadow
X = 12
18/24 = .75
16 x .75 = 12
3/4. triangle FHE and triangle KMN; triangle GEH and triangle LNM
1430 miles in 6.5 hours because you multiply 220 by 6.5 and equals 1430miles
