Answer:
y= 1/2x -1
Step-by-step explanation:
(0, -1), (2, 0)
y= mx + b
m= 1/2 (0.5)
b = -1
Answer:
Y= 5/3x + -9
Step-by-step explanation:
Well its
y=mx+b
m is slope
B is y intercept
To fidn y intercept, just make sure the X value of any coordiante given is 0 and the y value is not 0. So basically anything with (0, y), thats your y intercept.
Slope Is just
(y2-y1) / (x2-x1)
Answer:
Step-by-step explanation:
Principal, P = $4,000
Interest rate, r = 3% = 0.03
Period, t = 20 years
Number of times compounded in a year = 4
Amount , A = P( 1 + r/n)^tn
A = 4000( 1 + 0.03/4)^4*20
A = 4000( 1 + 0.0075) ^80
A =4000( 1.0075) ^80
A = 4000* 1.818
A = $7272.18
