the unit price per pound is $3.45
To find a linear question, we must have two points on the line and we must know the slope.
Let us choose two points at random:
(-6,12) and (-5,14)
Now let us find the slope of the linear line:

So the slope is 2.
Now let us set up the equation which now requires only one point and the slope
let us use the point (-6,12) and the slope of 2

So the linear line is y = 2x + 4.
Hope that helps!
Are you supposed to estimate or get an exact answer? If you're estimating you can see if the number is close to any perfect squares. In this case 63 is very close to 64, and 48 is very close to 49. The answers can then be estimated to be approximately 8 and 7, respectively.
Answer: 427 miles
Step-by-step explanation:
if the jeep averages 30.5 miles per gallon, and you have 14 gallons, then you will need to multiply 30.5*14 to get your answer, which is 427
