For the following:
In the rectangular coordinate system above, if x = 4.8, then y =
(A) 3.0
(B) 3.2
(c) 3.4
(D) 3.6
(E) 3.8
OA: B
If a line passes through (0,0) and (x,y), EVERY point on the line must have coordinates in the following ratio:
y/x.
The line in the figure passes through (0,0) and (3,2).
Thus, every point on the line must have coordinates in the following ratio:
y/x = 2/3.
Implication:
For every point on the line, y = (2/3)x.
Result:
When x = 4.8, y = (2/3)(4.8) = 3.2.
The correct answer is
B.
