Answer: y+3=-2(x-4)

Step-by-step explanation:

First, let’s find the slope. To do that just do (y2-y1)/(x2-x1). Substitute: (-3-2)/(3-2)= -5.

second, we want to put it in y=mx+b form so choose which coordinates you want to work with. Let’s say (2,1). So, 1=-5(2)+b

*(the one represents the y value, the -5 is slope and 2 is the x value)*

now just solve for b. b= 11

so the equation is: y=-5x+11

now, you can solve for the choices (I mean put them in y=Mx+b form) or just substitute in the coordinates to see which equation will work. In this case for choice w if we do 1+3=-2(2-4), that will be the answer.

Answer:

b

Step-by-step explanation:

1. find the slope

y2-y1/x2-x1

-3-1=-4

4-2=2

=-2-------this is our slope

point slope equation

y-y1=m(x-x1)

y+3=-2(x-4)

a certain state the license plate has two digits, then two letters, and then two digits. How many different license plates are p
xxTIMURxx [149]

Step-by-step explanation:

Choosing 4 digits out of 10 = 10C4 = 210.

Arranging the 4 digits in 4 places = 4!

Total number of ways to arrange digits

= 210 * 4! = 5040.

Choosing 2 letters out of 26 = 26C2 = 325

Arranging the 2 letters in 2 places = 2!

Total number of ways to arrange letters

= 325 * 2! = 650.

Total number of possible license plates

= 5040 * 650 = 3,276,000.
