Answer:
13
Step-by-step explanation:
We can use the slope formula to find the slope
m = ( y2-y1)/(x2-x1)
= ( -9-4)/(6-7)
= -13/-1
= 13
Answer:
an = 4n +5
Step-by-step explanation:
First we need to find a common difference
d = a2-a1 = 13-9 = 4
The formula for an
an =a1+d(n-1)
an = 9 + 4(n-1)
Distributing
an = 9+4n-4
Combine like terms
an = 4n +5
Answer:

I = prt
where i = interest, p = principal, r = interest rate, t = time
i = $1500 * 0.07 * 1.5
i = $157.5
