Answer:

y=-2

Step-by-step explanation:

Hello : let A(-3,-4) B(6,2)

the slope is : (YB - YA)/(XB -XA)

(2+4)/(6+3) = 6/9 = 2/3

an equation is the line is : y = ax+b a is a slope

y = (2/3)x+b

but this line passes by (6;2)

so : 2 = (2/3)(6)+b

b = -2

the equation is : y = (2/3)x-2

the the Y intercept of this line when : x= 0 so : y = (2/3)(0)-2

y=-2

If your question is how many positions are possible, then the answer is 24.

We find this by thinking of how many people can be in each spot. If there are 4 spots each person can stand (back left, back right, front left, front right), then there are 4 possible choice for the first spot (mom, dad, son, daughter), then 3 for the next spot (since 1 is already in a spot), then 2 options for the next spot, and then 1 option for the last spot. In other words, the answer is 4x3x2x1, or 4 factorial.
