A^2 + 16^2 = 20^2
(Third one)
Step-by-step explanation:
If y was directly proportional to x, the graph of y against x would pass through the origin (O).
Since the graph above does not show this, y is not directly proportional to x.
(4,3)(2,2)
slope = (2 - 3) / (2 - 4) = -1/-2 = 1/2
y = mx + b
slope(m) = 1/2
use either of ur sets of points...(4,3)...x = 4 and y = 3
now we sub and find b, the y int
3 = 1/2(4) + b
3 = 2 + b
3 - 2 = b
1 = b
so ur equation is : y = 1/2x + 1 <==
What is being solved for is r.
If you are going from least to greatest, it is 25.005, but if you are going from greatest to least, it is 20.505 .
Hope I helped
