Answer:
3
Step-by-step explanation:
sqrt9 = 3
Point-slope form of equation is: 
Step-by-step explanation:
Given points are:
(2,-8) and (1,7)
First of all we have to calculate the slope of the line
so,

Point-slope form is given by:

Putting the value of slope

We can put any one of two given points in the equation to find the final form of point-slope form
So
Putting (1,7) in the equation

Hence, point-slope form of equation is: 
Reducing and simplifying

Let m represent the number of miles traveled. If the whole budget amount of 370 is spent, then ...
... 190 + 0.25m = 370
... 0.25m = 280
... m = 280/0.25 = 1120
For 370, you can travel 1120 miles.
