  208

Step-by-step explanation:

First of all, it is useful to draw the factory location and the path the truck takes.

If you're paying attention, you will notice that the distance from each marked location to the origin is 3 grid squares horizontally and 4 grid squares vertically. This makes the distance to the origin be the hypotenuse of a 3-4-5 triangle, or 5 grid squares.

Then the distance diagonally from the warehouse to the airport is 10 grid squares. The distance horizontally from the airport to the factory is 6 grid squares, for a total distance of 10+6 = 16 grid squares.

You will notice the grid squares are marked as 13 miles each. The miles driven by the truck are ...

  (13 miles)(16) = 208 miles

_____

As you can see, it is helpful to notice when problems make use of 3-4-5 triangles.

If you want to compute this more or less directly, you can recognize the horizontal distance from warehouse to airport is 78 miles, and the vertical distance is 104 miles. The Pythagorean theorem tells you the diagonal distance is ...

 WA = √(78² +104²) = √16900 = 130

The distance to the factory is 78 miles, so the total is ...

  130 +78 = 208 . . . miles the truck drives

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

it's d
