For a particular cargo train, the amount of fuel needed for a trip varies directly with the number of miles traveled. if the train needs 300 gallons of fuel for a 100 mile trip, how much fuel does it need for a 750-mile trip?

2100 gallons

2150 gallons

2200 gallons

2250 gallons

question 5

given that a new fuel-efficient cars can drive 55 miles per gallon, how far can a car drive with nine gallons?

6.11 miles

455 miles

495 miles

540 miles

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?

slope is 35 and 20 miles is the y-intercept.
