Answer:
The answer to your question is: 30 miles can the car travel.
Step-by-step explanation:
Data
gasoline used = 11 1/2 gal
distance = 345 mile-trip
distance travel with 1 gal = ?
Process
Convert 11 1/2 to a improper fraction 11 1/2 = 23/2
Rule of three
23/2 gal ----------------------- 345 miles
1 gal ---------------------- x
x = (1 x 345) / 23/2
x = 345 / 23/2
x = 690/ 23
x = 30 miles
First we need to find the slope.
slope = (y2 - y1) / (x2 - x1)
slope = (-5 - 2) / (5 - -3)
slope = (-7) / (5 + 3)
slope = -7/8
.
Point-slope form:
y - y1 = m(x - x1)
y - 2 = (-7/8)(x - -3)
y - 2 = (-7/8)(x + 3)
y - 2 = (-7/8)x - 21/8
y = (-7/8)x - 21/8 + 2
y = (-7/8)x - 21/8 + 16/8
y = (-7/8)x - 5/8
