Answer:
A. -4/11
Step-by-step explanation:
Slope formula: 
Using the two points substitute the coordinates into this formula
6-2 = 4
4 - 7 = -11
Put 4 over -11 because it is the y value

A = 1/2h(b1 + b2)
2A = h(b1 + b2)
2A/h = b1 + b2
b1 = 2A/h - b2
618+5400=6018
6018+(50+2500)=8568
8568-(47+2900)=5621
she has $5,621 in her account
Answer:
the question is not complete
Quotient, implies division, so the quotient of 18 and 2 is 6:
18/2=6
Sum implies addition, so the sum of 22 and 9 is 31:
22+9=31
Now we can subtract the quotient of 18 and 2, '6', from the sum of 22 and 9, '31'.
31-6=25
Answer=25
