For any line with two points let's say (x1,y1) &(x2,y2),
slope(m)=(y2-y1)/(x2-x1)
In this case
(x1,y1)=(-8,4)
&
(x2,y2)=(4,-8)
So,
slope(m)=(-8-4)/[4-(-8)]
=-12/12
=-1
Answer:
put one and then put 0.5 in between 0 an 1
Step-by-step explanation:
Answer:
The equation is
n = PRT/100
The value of p
p = $1250
Step-by-step explanation:
Simple interest= n
Rate of interest = r
Number of years = t
Then principal amount= p
This p can be said to be the constant of the equation because it's value never changes
n = $225
r = 4.5%
t = 4 years
The interest varies jointly with the rate, the time and the principal amount.
The equation for the relationship
n > prt
But r is in percentage
n = PRT/100
For the value of p
p =(225*100)/(4.5 *4)
p= 22500/18
p= 1250
p = $1250
