To find the probability that the mom is at the front of the line:

\frac{number \: of \: favorable \: outcomes}{total \: outcomes} \\ = \frac{number \: of \: ways \: where \: mum \: is \: at \: the \: front \: of \: the \: line}{total \: number \: of \: ways} \\ = \frac{1c1 ×4! }{5!} \\ = \frac{24}{120} \\ = \frac{1}{5}
Therefore the answer is 1/5.

Hope it helps!

Complete the equation of the line through [1,4] and [2,2]
son4ous [18]

First find the slope of the line so change in y over change in x so 4-2/1-2 which is 2/-1 so -2 is your slope then plug that as well as a point from above to find your y intercept so y=mx+b 2=-2(2)+ b then you have 2=-4+b then add 4 to each side and you find b is six then you make ur equation from your slope and y int(b) y=-2x+6
