<h3>Answer: 5</h3>

=========================================================

One method is to plot the points P(3,6) and Q(7,3) on the same xy grid.  Plot a third point R at (3,3). See the diagram below.

A right triangle forms in which we can find the legs PR = 3 and RQ = 4. The hypotenuse is found through the pythagorean theorem.

a^2+b^2=c^2

3^2+4^2 = c^2

9+16 = c^2

c^2 = 25

c = sqrt(25)

c = 5

This is the length of PQ

-----------------------------------

Or you can use the distance formula which is effectively using the pythagorean theorem just in a slightly different format (though it may not be obvious).

d = \text{Distance from P to Q}\\\\d = \sqrt{(x_1-x_2)^2+(y_1-y_2)^2}\\\\d = \sqrt{(3-7)^2+(6-3)^2}\\\\d = \sqrt{(-4)^2+(3)^2}\\\\d = \sqrt{16+9}\\\\d = \sqrt{25}\\\\d = 5\\\\

Answer:

Option 2, (y = 4/6x - 4)

Step-by-step explanation:

Knowing that m acts as the slope in general, we can conclude that part of the equation is as such:

y = 4/6x

Now we are given coordinate (0, - 4) so that here x = 0 and y = - 4. Let's substitute these values into the prior equation:

y = 4/6x

-4 = 4/6(0)

-4 = 0

Now in order for y (-4) to be equal to the opposite side of the equation you would have to add -4:

-4 = 0 - 4

-4 = -4

That would mean the equation represents:

y = 4/6x - 4

The answer is C. Because the side triangles inner corner is 51 so the inner corner of the big train fled are 129. 129 + 20 equals 149 and 180 - 149 equals 31.
