The vertices of a triangle are A(4, 1).
B(9, 1), and C(2, 5). What is the area
of this triangle?
I need help with the equation i have already graphed this.

1. if we have 3 babies what is the probability they’re going to be all boys? 2. if we roll 2 die at the same time what is the probability of getting less than 10 on the first roll and a 5 on the second roll 3. if we have 3 babies what is the probability their is going to be 2 girls? 4. if we have 3 babies what is the probability of having no more than 1 girl? 5. it we have 3 babies and then have another 3 babies what is the probability of us having at least 1 boy and then having all girls?

Solve the given system of equations. 2y= -x+9 , 3x-6= -15
