Answer:
Step-by-step explanation:
Slope intercept form :
y = mx + b
m is the slope
b is the y-intercept
Let's look for m, use the formula 
to determine it.
Now find b, we simply need to plug in one of our coordinates to get our answer.
(12, -9)
Solve for b :
-9 = -6 + b
-3 = b
b = -3
Our slope intercept is :
Lets try to solve this problem using 2 equations, also,we will have bananas=b and pears =p
5b+3p= $3.80
2b+4p= $3.20 i will divide this equation by 2 and get
b+2p= $ 1.60 we subtract 2p from both side so i can find the cost for 1 banana
b+2p-2p=1.60-2p
b= $1.60-2p
I will replace the b in the first equation now,
5(1.60-2p)+3p=$3.80
8-10p+3p=3.80 solving for p
8-7p=3.80 we subtract 8 from both sides
-7p=-8+3.80
-7p=-4.20 we multiply both sides by (-1)
7p=4.20 we divide now both sides by 7
p=0.60 a pear cost 0.60 cents
a banana is b=1.60-2p, b=0.40 cents
Answer:
Yes
Step-by-step explanation:
I had this same question on a quiz and it is correct!
8x+6y=10
6y=10-8x
y=(10-8x)/6
