Corey walked three blocks east and then six blocks north. All the blocks were the same length. What is the value of the slope of the line from where Corey began walking to where he finished? -3
-2
2
3

-3

Step-by-step explanation:

i did the math

The slope is 2

Step-by-step explanation:

We are going to call (0,0) the point where Corey began walking. If he walked three blocks east he would be at the point (3,0), once there he walks 6 blocks north and make it to the point (3,6)

The slope m of the line that passes through point (0,0) and (3,6) is

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
