Slope = (7-2)/(3-0) = 5/3
slope intercept b = 2
equation y= 5/3x +b
<span>answer: B. y=5/3x + 2 </span>
Y=ax² + bx + c and A(-2,18), B(0.4), C(4,24) given
1)Let's determine 1st the value of c in using the pair of B
4= a(0)² + b(0) + c , c=4 and y=ax²+bx+4
2) Use the pair of A: 18 = 4a -2b + 4===> 4a-2b=14
3) Use C pair: 24 = 16a+4b+4 ==> 16a+4b=20
4) solve the system equation in 2) and 3) and you'll find a=2 and b=-3
Hence the equation is y =2x²-3x+4
A)

Answer: $998.67
Step-by-step explanation:
M = P[r(1+r)^n/((1+r)^n)-1)]
This does not include taxes, insurance, or PMI
