Answer:
(1/2)x + $5 (Answer A)
Step-by-step explanation:
Two points on the line representing the cost are (8, $9) and (12, $11).
The change in x is 4 (minutes); this is the 'run.' The change in y is $2 (this is the 'rise'). Thus, the slope of this line is m = rise / run = $2/(4 min), or 1/2 dollar per min.
Applying the slope-intercept formula y = mx + b, we get:
$9 = (1/2)(8) + b, and from this we see that b must be $5.
Then the correct equation is y = (1/2)x + $5.
Answer:
A:120
Step-by-step explanation:
Well it's not B or C or D so the logical conclusion is that it must be A.
The answer is A, y=-2.5x+54
