hello i see that no one has answered your question yet well im here to help:)
(1,-19),(-2,-7)
so here one way you can find the slope
i usually always use this to help me to keep it in order
------------------
(X1,Y1)(X2,Y2)
X2-X1
Y2-Y1
use this and your garanteed to get the right answer everytime
------------------
X = -2 – 1 = -3
Y = -7 – -19 = 12
once you do that you divide if possible
12/-3
which gives you -4
so your answer is -4
its really not hard you just got to get use to it
hope it help you:)

Answer: 7000
Step-by-step explanation:
Let the amount invested in 8% account be P1 and the amount invested in 6% account be P2
. If the total amount invested is $20,000 then:
P1+P2=20,000. (Eq. 1)
The interest earned in one year from the 8% account is:
I1=0.08P1
and the interest earned in one year from the 6% account is:
I2=0.06P2
If the total interest earned is $1460, then:
I1+I2=1460
0.08P1+0.06P2=1460
(Eq. 2) From Eq. 1 :
P1=20000−P2
Substituting this into Eq. 2:
0.08 (20000−P2) + 0.06P2 = 1460
1600 − 0.08P2 + 0.06P2 = 1460
0.02P2 = 140
P2 = 140 / 0.02
P2 = 7000
Hence, he invested $7000 at the rate of 6%.
