B.9 gallons in the gas tank and 280 miles.
From the given figure we see that the line of best fit passes through the point (13,400) and (17,520)
We know that the equation of a line passing through two point (a,b) and (c,d) is calculated by using the formula
y - b = d-b/c-a x (x-a)
Here we have:
(a,b)=(13,400) and (c,d)=(17,520)
Hence, the equation of line of best fit is: y - 400 = 520 - 400/17-3 x (x - 13)
y-400=120/4 x (x-13)
y=400=30x(x-13)
y-400=30x-390
y=30x-390+400
If u want to check your answers
0 gallons in the gas tank and 20 miles
when x=0 we have:
y=10≠20
Hence, option: A is incorrect.
B)
9 gallons in the gas tank and 280 miles .
when x=9 we have:
y=30×9+10
y=280
Hence, option: B is correct.
C)
11 gallons in the gas tank and 360 miles
when x=11; we have:
y=30×11+10
y=340≠360
Hence, option: C is incorrect.
D)
19 gallons in the gas tank and 520 miles
when x=19; we have:
y=30×19+10
y=580≠520
Hence, option: D is incorrect.
